摘要： A phase division multiple access (PDMA) system is provided. The PDMA system includes at least one receiver logic combiner adapted to generate a plurality of composite PN codes. Each of the plurality of composite PN codes are derived from a common composite PN code and are separated by a predetermined PN phase.

摘要： An apparatus for use with a baby stroller for supporting a cooling device, such as a fan or spray bottle, so as to cool a baby sitting therein. The support apparatus includes an elongate first support rod having a C-shaped clamp for coupling the first support rod to a stroller support member. The first support rod defines an elongate slot and a second C-shaped clamp movable therealong for coupling the first support member to another stroller support member. A length-adjustable support assembly is pivotally coupled to an end of the first support rod and includes telescopic sleeves. A second support rod is coupled to an upper end of the support assembly and is vertically displaced from the first support rod when the support assembly is pivotally positioned normal to the first support rod. The second support rod includes a third C-shaped clamp for snappably receiving a cooling device.

摘要： A transmitter is provided which simultaneously transmits waveforms such as with different data rates. These transmissions are modulated (e.g. phase modulated) onto quadrature channels of a common carrier, and are then combined. The resulting composite modulated waveform is upconverted to RF, power amplified, split and routed to separate ports for transmission. The transmitted signals are then received, downconverted and demodulated to produce the original signals.

摘要： A cutter shell for cutting a circular opening in a metal object formed of a tubular boring portion and a head portion. The boring portion has a tubular sidewall and teeth at the forward circumferential end. The sidewall is of thickness not greater than the teeth. The head portion has an outer circumferential perimeter secured to the tubular portion rearward circumferential end, the head portion being attachable to a boring bar by which the cutter shell is rotated. A circumferential abrasive band is affixed to the exterior circumferential surface of the tubular sidewall for engagement with the wall of a hole as the hole is cut in an object by the teeth to smooth and round out the hole for improved cylindricality.
