  • Patent number: 8562454
    Abstract: A connector of a golf club is provided. The connector includes a shaft adapter and a hosel adapter. A compression nut fits over both adapters to secure them against one another. The hosel adapter advantageously fits over the hosel, thereby allowing the bore of the hosel to remain unmodified from its original design. The connector also includes an anti-rotation arrangement to prevent relative rotation between the shaft adapter and the hosel adapter. Further, the tip end of the club shaft passes entirely through the connector and seats within the hosel as it normally would in the absence of the connector. The connector does not surround the tip end of the shaft where it seats in the hosel, giving the club an unaltered feel, despite the inclusion of the connector.

  • Patent number: 7400640
    Abstract: A novel implementation of a partitioned medium access control (MAC) is disclosed. The illustrative embodiment employs a shared bus that typically is already present in a wireless terminal for communication between an upper MAC and a lower MAC. The partitioned MAC implementation therefore does not require any additional communication means between the upper MAC and lower MAC, resulting in a lower-cost system. In addition, the upper MAC and lower MAC pass native data structures by reference over the shared bus, thereby eliminating the need for drivers to coordinate communication via interrupts, handshaking, etc. The partitioned MAC implementation results in a cost-effective distributed architecture in which the upper MAC resides in the terminal's host processor, and the lower MAC resides in the terminal's wireless station.

  • Patent number: 7352805
    Abstract: A method and system for enhancing reach-performance of a multi-carrier VDSL System estimates loop length, estimates maximum available bandwidth that can be utilized at that particular loop length, optimally selects an FFT size and sampling rate, and decides whether to apply a time domain equalization to its receiver and if so, selects a cyclic extension size. To minimize the implementation complexity, the sampling frequencies at receiver and transmitter are lowered to match the actual usable bandwidth. The FFT/IFFT sizes in the implementation are also required to set appropriately accordingly.

  • Patent number: 7263109
    Abstract: A method and system to minimize the potential of jitter buffer underflow/overflow resulting from a difference in sampling rates of an audio encoder and an audio decoder are disclosed herein. The difference in sampling rates, or clock skew, can be determined from a difference between an actual amount of data stored in a jitter buffer and the desired, or threshold, amount. A subset of packets from a sequence of packets output to the audio decoder can be altered to compensate for the clock skew, whereby the amount of data associated with the subset of packets is decreased when the sampling rate of the encoder is greater than the sampling rate of the decoder, and the amount of data is increased when the sampling rate of the encoder is less than the sampling rate of the decoder. The present invention finds particular advantage in providing audio data via a packet-switched network.

  • Patent number: 7254373
    Abstract: A wireless transceiver including multiple antennas, an antenna switch, and a media access controller that controls the antenna switch for determining when to switch to another antenna based on packet error rate (PER). Instead of switching the antenna on a packet-by-packet basis, antenna selection is made after one or more packets errors have been detected. The CRC is used to identify receive packet errors. A timer is used to determine each transmit packet error when an acknowledge packet is not received in time. A method of selecting from among multiple antennas including counting packet errors, comparing a packet error count with a threshold value to determine a threshold condition, switching to a different antenna if the threshold condition is met, and resetting the packet error count when the threshold condition is met.

  • Patent number: RE40231
    Abstract: A spread spectrum radio transceiver includes a high data rate baseband processor and a radio circuit connected thereto. The baseband processor preferably includes a modulator for spread spectrum phase shift keying (PSK) modulating information for transmission via the radio circuit. The modulator may include at least one modified Walsh code function encoder for encoding information according to a modified Walsh code for substantially reducing an average DC signal component to thereby enhance overall system performance when AC-coupling the received signal through at least one analog-to-digital converter to the demodulator. The demodulator is for spread spectrum PSK demodulating information received from the radio circuit. The modulator and demodulator are each preferably operable in one of a bi-phase PSK (BPSK) mode at a first data rate and a quadrature PSK (QPSK) mode at a second data rate. These formats may also be switched on-the-fly in the demodulator. Method aspects are also disclosed.
