A probe is configured for introduction into a vicinity of a hazard. The probe comprises multiple sensors, communications circuitry, processor circuitry, and a casing. The multiple sensors include at least: a sensor configured to acquire disposition information of the probe; and a sensor configured to acquire environmental information in a vicinity of the probe. The communications circuitry is configured to transmit the disposition information and the environmental information externally to the probe. The processor circuitry is configured to coordinate operation of the multiple sensors and the communications circuitry. The casing is configured to internally house the multiple sensors, the transmitter, and the processor circuitry. The casing comprises an essentially cylindrical bullet shape, and wherein along a major cylindrical axis a first end of the casing comprises a flat butt surface and a second end of the casing comprises a rounded nose surface.

Disclosed herein is a wireless transmitter system which provides a small, frequency agile wireless microphone transmitter allowing active performers to have a wireless transmitter system without the inconvenience of a large transmitter. The wireless receiver of the wireless transmitter system comprises a large backlit display, simple operation with auto-scan channel selection, and infrared set for syncing the wireless microphone transceiver and wireless receiver. The wireless transmitter system is simple and easy to set up and operate. The wireless transmitter system further ensures clear, interruption-free performance by utilizing a True RF Diversity design with a pilot tone-key and auto-mute function. This provides maximum operating distance along with eliminating any background noise when the wireless microphone transceiver is out of range or powered off.

A first device such as a wristwatch may include a front face at which a display is disposed and a rear face at which a rear housing wall is mounted. Antenna structures may overlap the rear housing wall and may be operable to transmit and receive relatively high frequency signals through the rear housing wall to a communication with a second device such as a wireless power transmitting device for the wristwatch. The second device may also include antenna structures that overlap a top surface housing. Respective sets of magnetic structures may be provided in the first and second devices to align the two devices and to form a reliable wireless communication link between the two devices. The first and second devices may include respective antenna arrays that include pairs of antenna elements that are selectively used to form a reliable wireless communication link.

Typically, the displacement of piezo-electric actuators is quite small. Accordingly, some sort of amplification may be needed for specific applications to amplify the displacement of the piezo-electric actuator, and thereby amplify the haptic feedback. For all solutions, the goal is to amplify the displacement of a moveable mass in order to increase vibration to improve the haptic feedback. If the host device is a wearable or portable device, e.g. a smart watch, it would be preferable to excite a heavy moveable mass that is already part of the assembly to harvest enough energy to transmit to the interface with the user. If the device is a large display, e.g. a display in a vehicle info system, the display itself could be the moveable mass.

A transmitter comprises a main body case, a controller that is provided inside the main body case, a communication unit that is connected to the controller, and an elongated antenna unit that is connected to the communication unit. The antenna unit is disposed along an inner wall surface of the main body case.

In one example, an electronic device may include a housing having an opening and an antenna assembly disposed in the housing. The antenna assembly may include an antenna mounted to the housing, an antenna module disposed corresponding to the opening, and a cable to connect the antenna to the antenna module via routing the cable through the opening.
