Method, modules and a system formed by connecting the modules for controlling payloads are disclosed. An activation signal is propagated in the system from a module to the modules connected to it. Upon receiving an activation signal, the module (after a pre-set or random delay) activates a payload associated with it, and transmits the activation signal (after another pre-set or random delay) to one or more modules connected to it. The system is initiated by a master module including a user activated switch producing the activation signal. The activation signal can be propagated in the system in one direction from the master to the last module, or carried bi-directionally allowing two way propagation, using a module which revert the direction of the activation signal propagation direction. A module may be individually powered by an internal power source such as a battery, or connected to external power source such as AC power. The system may use remote powering wherein few or all of the modules are powered from the same power source connected to the system in a single point. The power may be carried over dedicated wires or concurrently with the conductors carrying the activation signal. The payload may be a visual or an audible signaling device, and can be integrated within a module or external to it. The payload may be powered by a module or using a dedicated power source, and can involve randomness associated with its activation such as the delay, payload control or payload activation.

A communication system includes a plug module having a plug housing and a plug latch and a receptacle module having a receptacle housing and a receptacle latch. The receptacle module includes a receptacle connector with a card slot receiving a plug module circuit board. The receptacle connector includes cables terminated to contacts and extending from the receptacle connector. A receptacle cage includes a front cage interface receiving the plug module and a rear cage interface receiving the receptacle module. The front cage interface matches the rear cage interface including a front latching feature and a rear latching feature interfacing with the plug and receptacle latches.

A system provides a “virtual room” for remotely sharing content experiences via electronic devices at different locations. The system may enable synchronization of the content at the different locations, access control, be able to provide and/or experience interaction feedback regarding the content, control the interaction feedback that is provided and/or experienced, enhance the ability of people to distinguish the content from the interaction feedback, and so on. As such, people may be able to share content experiences more like they were present in a single location while remote from each other.

A vehicle power adaptor module includes a vehicle-sided connector and an interchangeable socket. The vehicle-sided connector includes a connector body and a first connecting portion. The first connecting portion is connected with the connector body. The connector body is configured to electrically connect with an electric vehicle. The interchangeable socket includes a socket body and a second connecting portion. The second connecting portion is connected with the socket body. The socket body is configured to electrically connect with an electronic equipment. The second connecting portion is configured to detachably connect with the first connecting portion.

A battery charger and method is disclosed for detecting when a battery has a low state of health while simultaneously charging or maintaining the battery. A battery charger includes a processor; a non-transitory memory device; a power management device to receive an input power and to output a charging current; a pair of electrical conductors to electrically couple with a battery, and a display electrically coupled to the processor. The display being configured to indicate a bad battery indicator when the battery has a low state of health and whether the battery is good to start.

The present invention is a wireless HVIL system and method using RFID-enabled Electrical Connector with connector position assurance (“CPA”) features. Each RFID-enabled Electrical Connector has an RFID tag that is only readable after the CPA features of the RFID-enabled Electrical Connector have been fully deployed. If a CPA feature has not been fully deployed, electrically conductive material will obscure the RFID tag so that it cannot be read. At least one RFID reader is distributed so that all of the RFID tags are within its effective range. When system power is cycled on, the at least one RFID reader emits a digital pulse and reads all of the non-obscured RFID tags. If the at least one RFID reader detects all of the expected RFID tags, an HVIL processor will shut an HVIL switch, and power will be supplied to all HV devices.

The present invention is an RFID-enabled electrical connector with connector position assurance (“CPA”) features. The RFID tag is only readable after the CPA features have been fully deployed. The electrical connector is comprised of at least two parts, a socket and a plug. In the illustrated embodiment, a connector housing is positioned between the socket and plug, with both the socket and plug connecting to the connector housing. Until the CPA feature has been fully deployed, the RFID tag is covered by an electrically conductive material, preferably an electrically conductive plastic. The RFID tag can only be properly read after the CPA feature has been fully deployed. To prevent signal leakage, the RFID tag can alternately be placed inside a five-sided box fabricated from electrically conductive material, preferably electrically conductive plastic.

A battery detection system includes a battery assembly and an electronic device. The battery assembly includes a first connector and a detection module connected to the first connector. The electronic device includes a second connector and a control module connected to the second connector. When the first connector is connected to the second connector, the detection module is configured to output first identification information to the electronic device through the first connector. When the second connector receives the first identification information, the control module confirms that the battery assembly is in a connected state. After the first connector is disconnected from the second connector, the detection module generates and outputs second identification information. When information received by the second connector changes from the first identification information to the second identification information, the control module confirms that the battery assembly is disconnected.
