A trolley wheel mechanism has two caster wheel assemblies each having a pair of wheels mounted on a rotatable housing. In a free mode the wheels are free to both rotate and to swivel. This is caused by the user pressing a release pedal. In a unidirectional mode a retainer lock engages a brake disc to prevent swivelling of the housing. This is caused by the user pressing both pedals simultaneously. A brake mode is caused by the user pressing the apply pedal.

A system, such as a satellite reception assembly or customer premises gateway, may comprise an analog-to-digital converter operable to digitize a signal spanning an entire television spectrum (e.g., cable television spectrum or satellite television spectrum) comprising a plurality of television channels. The system may comprise a signal monitor operable to analyze a signal to determine a characteristic of the signal. The system may comprise a data processor operable to process a television channel to recover content carried on the television channel. The system may comprise a channelizer operable to select first and second portions of the signal, and concurrently output the first portion to the signal monitor and the second portion to the data processor.
摘要:
Systems, methods, apparatus, processors and computer-readable media include a radiated testing module that executes a predetermined radiated performance test on a wireless device. The test dictates various performance-related parameters to measure and log at each of a plurality of predetermined positions. Further, the wireless device receives synchronization information operable to enable synchronization between the logged measurements and each of the positions. The synchronized log allows the wireless device, or another apparatus, to determine a radiated performance characteristic based on a predetermined analysis protocol. Further, the described embodiments allow for the determination of several radiated performance characteristics in a single test, using a single, unaltered wireless device.

摘要:
An underlayment for supplementing one or more physical properties of wall, ceiling, and floor construction components is used to in a wall, ceiling, or floor assembly that may be fabricated on site. The assembly includes: first and second wall, ceiling, or floor construction components which each have physical properties and an underlayment component which has at least one supplemental physical property for supplementing the physical properties of the first and second construction components. The construction components may or may not be secured together with the underlayment sandwiched between the second and first construction components to form a wall, ceiling, or floor assembly with the supplemental physical property or properties of the underlayment. The supplemental physical property or properties of the underlayment may include, but are not limited to, latent storage of thermal energy, sound transmission reduction, and/or burn through resistance.

摘要:
A tuner includes, in part, one or mixers, one or more filters, one or more variable gain stages, one or more analog to digital converters, and a baseband processor. Each filter is responsive to an associated mixer's output signal. Each variable gain stage is responsive to an associated filter's output. Each analog-to-digital converter is adapted to convert the output signal of an associated variable gain stage to a digital signal. The baseband processor is responsive to the digital signal supplied by the analog-to-digital converter(s). The baseband processor is further configured to supply a signal to be demodulated by a processing unit external to the integrated circuit. The baseband processor performs no or a fraction of the required demodulation functions. The processing unit may be a central processing unit or a graphical processing unit.
