Wireless transceiver for controlling professional lights and special effects devices

Abstract

This invention provides a wireless transceiver device for retrofit conversion of non-wireless enabled electronic controllers and controlled host devices. This invention allows for the rotating of the wireless transceiver device allowing for the entire device to rotate around the connector axis. This functionality allows for the ability to rotate the wireless transceiver device 360 degrees or to any orientation that maximizes the available space around the host device or around the area of permanent or temporary installations of networks of single or multiple controllers and controlled devices. The inclusion of a stop pin washer plate may be combined with a rotation limiting washer to prevent the rotating assembly from moving freely around the 360 degrees of rotation.

The wireless transceiver device 100 may include an LCD screen or other visual display screen (not shown).

(15) The wireless transceiver device 100 can operate on any practical wireless protocol (e.g., WiFi, CRMX, W-DMX, Ethernet, Bluetooth, Zigbee and/or near field RFID. However, in its most practical application, the wireless transceiver device 100 typically operates using the DMX512 wireless protocol standard that is commonly used to control stage lighting and special effects devices. The signals transmitted via the wireless protocol can be encrypted for added security so that intentional or un-intentional interference in the wireless transceiver device's operation is minimized. The wireless transceiver device 100 can convert any controlled lighting device or special effects device into a wireless device that can be controlled by a controller. Using DMX512, the range can be up to a quarter mile and may employ frequency hopping to reduce interference and provide a certain level of security.

(16) The wireless transceiver device 100 comprises internal electronic components further comprising a radio frequency (RF) module that allows the wireless transceiver device 100 to act as a receiver, transmitter or a transceiver. The wireless transceiver device 100 can employ the functionality of a receiver, transmitter or a transceiver with user controlled switches allowing for the user to select its mode of operation.

(17) FIG. 2 is a top view of the wireless transceiver device 200 for controlling professional stage and movie lighting and effects.

(24) FIG. 9 is a perspective rear view of the wireless transceiver device 900 with an adaptor 902 for controlling professional stage and movie lighting and effects. An external DC power connector 904 may be mounted to the chassis 906 or cover 908. The chassis 906 can be fitted with a chassis cover 908 to prevent damage or interference with internal components that do not require user accessibility for operation. The power connector can facilitate the connection of an external AC power source to a direct current (DC) transformer power source which is used by the internal circuit board assembly. Various embodiments can accept voltages from a USB style adapter or by any plug in transformers adapter that is well known in the art. The power voltage ranges can vary from 4 volts to 48 volts. An alternate embodiment may include an internal power source supplied by batteries, solar power cells, or a connector for receiving power from the host device, Power over Ethernet (PoE) or other wireless power source, and/or power supplied through unused connector pins on the DMX connector.

(25) The wireless transceiver device 900 may also employ a wireless unlink or wireless disconnect button 910 that can be used to reset the device 900 to a standard wireless protocol established by the manufacturer or pre-selected by the user. Antenna 912 is connected to the wireless transceiver device 900 by connector 914.

(26) FIG. 10 is a perspective front view of the wireless transceiver device 1000 for controlling professional stage and movie lighting and effects. The wireless transceiver device 1000 has housing or chassis 1002 and cover 1004 to protect the internal components of the device from weather or other damages. The internal components can provide impact protection to insulate the fragile electronic modules contained within the housing 1002.

(27) In this embodiment, the adaptor 1006 is mounted on the bottom or the wireless transceiver device 1000. FIG. 10 illustrates an optional power connection 1008 and a wireless unlink button 1010 that can reset the operation of the wireless protocol. Other functions shown in FIG. 10 include a mounting collar 1012 for mounting industry standard hardware and a wireless connector 1014 for mounting the antenna 1016. The mounting collar 1012 may be installed into the chassis cover or the housing 1002. The mounting collar 1012 allows for standard mounting hardware connections to the chassis to maximize the flexibility of use. In one embodiment, the mounting collar 1012 may accept an industry standard baby pin mounting part. A traditional cable may be used to connect a host device to the wireless transceiver device as it may need to be mounted with any industry standard clamps in a position away from the host device to maximize wireless signal strength.

(28) FIG. 11 is a perspective expanded parts view of the wireless transceiver device for controlling professional stage and movie lighting and effects. The wireless transceiver device 1100 can include a rotating assembly for the interface connector 1102 that supports and allows for angular positioning around the axis of the interface connector adaptor 1102 after it is plugged into a host device (not shown). This subassembly may comprise two plastic or other low-friction material washers 1104 assembled onto the interface connector adaptor 1102 around the chassis cover 1106. These washers 1104 allow the interface connector adaptor 1102 to smoothly rotate in the chassis cover or housing 1106 with low applied torque from the user. The chassis cover 1106 rotates around a pivot point where the pivot point is an axis that bisects the interface connector adaptor 1102.

(29) In one embodiment, on the interior and behind the washer 1104, a stop washer 40 is assembled to the DMX connector. This stop washer 1108, combined with the stop pin 1110 mounted to the cover 1106, acts to prevent the rotating interface connector assembly 1102 from moving freely around 360 degrees of rotation around the device 1100. For example, in one embodiment, the tab protruding from the stop washer 1108 may be designed such that only 270 degrees of rotation are possible before an edge of the tab comes in contact with the stop pin 1110 thus preventing further movement. Such a design can act to prevent excessive twisting and stress applied to the internal wiring of the device 1100.

(30) The design specifies the location of the stop pin 1110 relative to the housing or chassis 1112 and stop washer as well as the size and shape of the stop washer 40 tab to meet rotational limitations as needed for each embodiment. A wave washer 1114 can be included in the assembly as can an insulating washer 1116. The wave washer 1114 can be compressed through spacer 1118 by threading and tightening the interface connector adaptor end cap 1120 onto the interface connector adaptor 1102 threaded end that passes through the cover 1106. The wave washer 1114 provides a spring force in the axial direction to maintain friction at the thread interfaces of the cap and connector thus preventing the assembly from loosening when it is rotated. A washer 1116 may be inserted into the assembly to provide compression for the wave washer 1114 that provides sufficient resistance to unwanted motion. While easily adjustable without specialized tools, the assembly can be made stiff enough to prevent unwanted rotation once connected.

(31) An alternate embodiment may combine or eliminate some components of the rotation assembly while still maintaining the intent of rotation of the device around the axis of the rotating interface connector assembly 1102. In another embodiment of the rotating assembly components may allow for full 360 degree rotation around the rotating interface connector assembly 1102 axis through the use of a stator and communicator assembly or slip ring and brush component or other suitable contacts.

(32) In alternate embodiments, the housing or chassis 1112 may allow for mounting the rotating interface connector assembly 1102 on either the chassis cover 1106 or the chassis itself. Also, the rotating interface connector assembly 1102 can be located on the bottom of the wireless transceiver device 1100 as previously shown. To optimize manufacturing flexibility and efficiency a rotating interface connector assembly 1102 mounting position hole may be present on both the chassis 1112 and cover 1106 with an optional hole plug 1122 installed in the unused hole upon assembly of the system.

(33) The chassis 1112 provides location and mounting for a RF circuit board module 1124 inside the housing or chassis 1112. A wireless network antenna interface connector 1126 may be mounted to the housing or chassis 1112 or the cover 1106 in some embodiments. Alternate embodiment may have internal antennas. A removable and directionally adjustable wireless antenna 1128 is mounted to the antenna interface connector 1126. Also connecting to the RF circuit board or other electronic circuitry modules are a power connector 1130 and an optional wireless unlink button 1132.

(34) The advantages of the invention include, without limitation, the ability to replace cabling used in a wide range of lighting and effects control applications. Reductions in cabling complexity and material cost, setup time and labor costs are benefits of the wireless transceiver device. A general design feature of the various embodiments of the wireless transceiver device is such that host device onto which the wireless transceiver is connected requires no modification, alteration or additional parts for full functionality.

(35) FIG. 12 is a perspective expanded parts view of another embodiment of the wireless transceiver device for controlling professional stage and movie lighting and effects. The device includes a rotating assembly to allow for angular positioning around the axis of the DMX interface connector/interface adaptor 1200 after it is plugged into a host device. The subassembly may comprise one or more plastic or other low-friction material washer(s) 1202 assembled onto the DMX connector 1200 around the chassis 1204. These washer(s) allow the DMX connector 1200 to smoothly rotate in a chassis 1206 with low applied torque from the user. Thus, the chassis 1206 can rotate around a pivot point where an axis of the pivot point bisects the DMX connector 1200.

(36) In one embodiment, on the interior and behind the washer(s) 1202, a stop pin washer 1208 is assembled and positioned adjacent to the DMX connector 1200. In alternate embodiments, the low friction washer(s) 1202 may be positioned behind the stop pin washer plate 1208. The stop pin washer plate 1208 may be combined with a rotation limiting washer 1210 and acts to prevent the rotating assembly from moving freely around 360 degrees of rotation.

(37) For example, in one embodiment, the pin protruding from the stop pin washer plate 1208 may be designed such that less than 360 degrees of rotation is possible (e.g., 270, 180, or 90 degrees of rotation) before an edge of the tab feature on the contact rotation limiting washer contacts the pin and prevents further movement. The stop pin washer plate 1208 in turn may be designed to lock in place on a screw, pin, or protrusion in the lid or other such feature so it is prevented from turning. This is designed to prevent excessive twisting and stress applied to the wiring to the DMX connector 1200. The design specifies the location of the stop pin washer 1208 relative to the chassis 1206 as well as the size and shape of the rotation limiting washer 1210 tab to meet rotational limitations as needed for each embodiment. An electrically insulating washer may optionally be included in the assembly, followed by a spacer 1212 by threading and tightening the DMX connector end cap 1214 onto the DMX connector 1200 threaded end.

(38) While easily adjustable without tools, the assembly can be made stiff enough to prevent unwanted rotation. In summary, the DMX connector rotating assembly comprises the connector 1200, one or two low-friction washers or bearings 1202, a stop pin washer 1208, a rotation limiting washer 1208, an optional insulating washer (not shown), a spacer 1212 and finally the DMX connector end cap 1214. An alternate embodiment may combine or eliminate some components while still maintaining the intent of rotation of the device around the axis of the DMX connector 1200.

These washers allow the DMX connector to smoothly rotate in the chassis cover 1204 with low applied torque from the user. In one embodiment, on the interior and behind the low friction washer 1202, a stop pin washer 1208 is assembled to the DMX connector 1200.

(40) In alternate embodiments, the low friction washer 1202 may be behind the stop pin washer 1208. The stop pin washer 1208 is combined with a rotation limiting washer 1210 and acts to prevent the rotating assembly from moving freely around a 360 degrees of rotation. For example, in one embodiment, the pin protruding from the stop pin washer 1208 may be designed such that only 270 degrees of rotation are possible before an edge of the tab feature on the contact rotation limiting washer contacts the pin and prevents further movement.

In summary, the DMX connector rotating assembly comprises of the connector 1200, one or more low-friction washer(s) or bearings 1202, a stop pin washer 1208, a rotation limiting washer 1210, an optional insulating washer, a spacer 1212 and finally the DMX connector end cap 1214.

(42) An alternate embodiment may combine or eliminate some components while still maintaining the intent of rotation of the device around the axis of the DMX connector. Another embodiment of the rotating assembly components may allow for full 360 degree rotation around the DMX connector axis through the use of, for example, a stator and commutator assembly, slip ring and brush components or other suitable contacts.
