The disclosure relates to a hand control input device, comprising a housing, wherein the housing is internally provided with an interface chip for communicating with a terminal equipment. The housing is further internally provided with: a first z-axis signal collector for generating a first z-axis signal containing a first pressure value and a first identifier; a second z-axis signal collector for generating a second z-axis signal containing a second pressure value and a second identifier; a z-axis signal processor, connected with the first z-axis signal collector, the second z-axis signal collector, and the interface chip for extracting the first pressure value from the first z-axis signal and the second pressure value from the second z-axis signal, calculating, according to the first pressure value, the second pressure value and the sampling period, a z-axis displacement variation value for controlling a displacement variation of a controlled object in an interface space of the terminal equipment in a positive direction and negative direction of z-axis, and transmitting the z-axis displacement variation value via the interface chip. The hand control input device can realize the displacement control of the controlled object along the direction of the z-axis.

Securing device rejoining for a mesh network of a wireless lighting control system is disclosed. A potential security weakness of a mesh network protocol is that a proprietary link key may be discovered by close, expert examination of a device, potentially facilitating the joining of a “rogue” device to the network. Requiring subsequent rejoins of any device that had previously joined the network to use a current randomly generated link key, rather than the proprietary link key, prevents rogue devices only having the proprietary link key from joining.

A modular light fixture includes an elongate light fixture base having a longitudinal axis and a plurality of light fixture modules. Each light fixture module includes a housing having an open face, and a light emitting device positioned inside the housing. The modular light fixture also includes a light emitting device driver configured for driving the light emitting devices. The light fixture modules are independently mounted to the light fixture base and extend perpendicularly from opposing sides of the light fixture base with the open faces facing a common direction to produce an initial light distribution pattern. Each light fixture module has a housing adjustment feature for independently pivoting the light fixture module about a pivot axis parallel to the longitudinal axis to modify the initial light distribution pattern. The modular light fixture includes a planar configuration in which the light fixture module housings are oriented along a common plane.

A multi-band antenna includes a ground plane, and a radiating unit including an L-shaped first radiating arm, a U-shaped second radiating arm, a feed-in arm and a coupling arm. The first and second radiating arms are connected to the ground plane, and have respective free end portions that are spaced apart from and overlap the ground plane, that face each other, and that define an opening in spatial communication with an inner space defined by the first and second radiating arms and the ground plane. The feed-in arm is disposed in the inner space between the first radiating arm and the ground plane, is connected to the ground plane, and overlaps the opening. The coupling arm is connected to the connecting segment, and overlaps the free end portions.

A dual-pixel circuit includes first and second OLEDs, and a driving circuit that includes first and second driving transistors, a capacitor, and a switching module operable between first and second modes based on a data voltage, first and second scan voltages, and first and second bias signals. When the switching module is operated in the first mode, the first OLED is forward-biased to emit light, and the second OLED is reverse-biased. When the switching module is operated in the second mode, the first OLED is reverse-biased, and the second OLED is forward-biased to emit light.

A liquid dispensing applicator has a container body holding liquid, a longitudinal axis for rotation and an offset projection located to avoid traversing the longitudinal axis. The applicator also has a head component receiving an end of the container body and has a slot system for receiving the offset projection. The container body and the head component are rotatable with respect to each other to cause the offset projection and the slot system to engage and break the offset projection, allowing liquid release through the head for application. The applicator may have an axial locking system and a radial locking system for locking the container body and the head component together at various positions for improved stability, alignment or reliability.
