Abstract: A wireless microphone system comprises system equipment (for example, rack-mounted equipment including receivers/transceivers, distribution amplifier), one or more transmission line accessories, and a transmission line network connecting the accessories with the system equipment. The transmission line accessory compensates for downlink RF losses on transmission lines between accessories and between an accessory and system equipment. Compensation parameters for the transmission line accessory is determined by the system equipment by generating an uplink RF test signal by an RF source at the system equipment. The RF source may be varied over a plurality of frequencies to determine the compensation parameters over the plurality of frequencies. The system equipment subsequently instructs the transmission line accessory to configure an adjustable RF gain circuit (and also possibly a compensation filter) accordingly.

Abstract: An electronic controller for a variable ratio transmission and an electronically controllable variable ratio transmission including a variator or other CVT are described herein. The electronic controller can be configured to receive input signals indicative of parameters associated with an engine coupled to the transmission. The electronic controller can also receive one or more control inputs. The electronic controller can determine an active range and an active variator mode based on the input signals and control inputs. The electronic controller can control a final drive ratio of the variable ratio transmission by controlling one or more electronic solenoids that control the ratios of one or more portions of the variable ratio transmission.

Abstract: Devices and methods are disclosed for generating, filtering, and amplifying signals that are sent and received using SOCs. These improved methods and devices advantageously provide filtering of composite RF signals such that the RF signals can be transmitted with an improved SNR. Such filtered signals can then be transmitted at a higher power. Because filtering is performed at an intermediate frequency, the higher cost of low-noise RF-transmitters and/or RF filtering components can be avoided. Accordingly, less expensive (e.g., noisier) components, such as readily available wireless transceiver SOCs, can be used for generating RF signals, filtering the signals, and then transmitting the filtered signals at higher power. As a result of these devices and methods, inexpensive SOCs may be used at higher powers and over longer ranges than would be normally expected.

Abstract: A locking cable device, which generally inhibits the theft of portable and more specifically inhibits the theft of expensive, electronic devices such as computers, laptops, and projectors. The security device works by use of a hook that hooks through an opening in an outside wall of the equipment to be secured. The hole can be an existing hole in the outside wall of the equipment, either round, square, or rectangular, such as a vent slot or security slot. A user may also add the opening by merely drilling an aperture or slot, sized appropriately for the corresponding hook on the security device. The hooked position is maintained by use of a housing locked on to the cable, close enough to the equipment being secured that the hook cannot be moved to an angle necessary for removal.

Abstract: In one embodiment, a computer-aided dispatch (CAD) system includes a database for storing data originated at a plurality of CAD stations; a manager that manages access to the data stored in the database; and the plurality of CAD stations communicatively connected to the manager and to each other. While the manager is available, each CAD station transmits the critical data and the non-critical data originated at the CAD station to the manager and receives the critical data and the non-critical data originated at one or more other CAD stations from the manager. While the manager is unavailable, each CAD station transmits the critical data originated at the CAD station directly to all other CAD stations and receives the critical data originated at the one or more other CAD stations directly from the one or more other CAD stations.

Abstract: In one embodiment, a computer-aided dispatch (CAD) system includes a database for storing data originated at a plurality of CAD stations; a first manager that manages access to the data stored in the database; one or more second managers communicatively connected with the first manager; and the CAD stations. Each one of the second managers is communicatively connected with particular ones of the CAD stations. The particular ones of the CAD stations communicatively connected with the same second manager are communicatively connected with each other. For each one of the second managers communicatively connected with the particular ones of the CAD stations: while the second manager is available, the particular ones of the CAD stations exchange data via the second manager; and while the second manager is unavailable, the particular ones of the CAD stations exchange data directly with each other.
