Abstract: A remote control device is disclosed. A single-piece casing has a first opening at one end, a second opening at another end, an inner cavity between the first and second openings, and a front opening and key openings in a front surface. A keypad is disposed within the inner cavity and has keys arranged on a surface of the keypad which extend through the key openings. A chassis body is inserted into the inner cavity though the first opening and below the keypad. The chassis has an end part located outside of the casing. An edge of the end part is configured to abut against one end of the casing. An end insert body is inserted into the inner cavity though the second opening, below the body of the chassis. The end insert has an end part located at the another end of the casing.

Abstract: An apparatus, system, and method for an automatic dimming and color adjusting backlight LEDs of wall mounted control device buttons. The control device comprises a light sensor that detects light levels in a room where the control device is installed. The control device comprises a controller that operates the backlight LEDs according to day color setting when it receive a light level reading from the light sensor that is above a day/night threshold and according to a night color setting when it receives a light level reading from the light sensor that is below the day/night threshold. In addition, the controller dims the backlight LEDs based on the detected light level readings according an indication mode dimming curve when the backlight LEDs are in an indication mode and according to a backlight mode dimming curve when the backlight LEDs are in a backlight mode.

Abstract: Described herein is a triangle wave generator circuit for use with a class D amplifier, the triangle wave generator circuit adapted to generate and output a triangle wave signal and comprising: a clock generating circuit adapted to provide a timing signal that generates a period of the output triangle wave; a first current source adapted to provide a first source current at a first magnitude; a first current sink adapted to sink a first sink current at about two times the first magnitude; a DC servo circuit adapted to adjust the first magnitude of the first source current based on a direct current (DC) voltage present in the output triangle wave signal so that the DC voltage on the output triangle wave signal is substantially eliminated; and an output filter circuit adapted to substantially reduce audio frequency noise in the output triangle wave, and generate the output triangle wave signal at a desired peak-to-peak voltage level based on the first source current and first sink current.

Abstract: A cable retractor includes a frame having first and second frame ends, opposing frame walls between the frame ends, and a track extending along one of the frame walls. A block slides along the track. A single first pulley is coupled to the block, is rotatable about a first axis that moves together with the block, is the sole pulley that is rotatable about the first axis, and has only a single groove. A spring spool is mounted at the first frame end. A spring has a coiled part wound around the spring spool and has a segment that extends away from the coiled part and is coupled to the block. A single second pulley is disposed at the second frame end, is rotatable about a fixed second axis, is the sole pulley that is rotatable about the second axis, and has only a single groove.

Abstract: A hot-desking system includes a hot-desking station, including a hot-desking station device, and a hot-desking panel configured to display information regarding status of the hot-desking station and a 2D code associated with the hot-desking station. A docking station associated with the at least one hot-desking station includes input and output ports connected to the hot-desking station device. A hot-desking portal controls operation of and configuration of the hot-desking station, the docking station, and the hot-desking panel.

Abstract: A method and apparatus to verify connection between a first and second electronic device is described herein, comprising: an ethernet cable connected at a first end to a first device at a first connector and connected at a second end to a second device at a second connector, and wherein the ethernet cable comprises four twisted pairs of conductors; a voltage source in the first device connected to a first end of a first conductor of a first twisted pair in the ethernet cable; a resistor with a first known resistance value located in the second device connected at a first end of the resistor to a second end of the first conductor of the first twisted pair and a second end of the resistor connected to a second end of a second conductor of the first twisted pair; a connection verification circuit located in the first device connected to a second end of the second conductor of the first twisted pair of the ethernet cable, wherein the connection verification circuit is adapted to generate a connection verification

Abstract: An electronics box for insertion into a wall box includes a housing having walls that define an inner volume of the housing. A wall includes an edge having part disposed along an outer surface of that wall, and a tab disposed within the inner volume at a first predetermined distance from the outer surface of the wall and extending along a direction parallel to the outer surface of the wall past the edge. Another wall includes an edge having a part along an outer surface of that wall, and an opening completely surrounded by the wall at a second predetermined distance from that edge. Upon the parts of the edges of the walls being brought in contact, the tab is inserted into the opening, the tab and the opening being dimensioned such that the tab securely fits into the opening and secures the walls together.
