Title: Rapid synchronization for communication systems
Inventor: MCCALLISTER RONALD D
IPC: H04W84/14
Filed: 1999-06-02
Abstract: Different subscriber units (14) transmit different burst signals to a base station (12) on a common frequency to which a base station demodulator (64) is already synchronized. The base station (12) transmits constant values .alpha . and , where .alpha. is multiplied by a base station reference frequency to achieve a base station transmitting frequency, and  is multiplied by the reference frequency to achieve the base station (12) receiving frequency. A subscriber unit (14) synchronizes to the base station transmitting frequency . As a result of the synchronization process, the subscriber unit (14) determines a value .beta., which, when multiplied by a subscriber unit reference frequency, achieves the subscriber unit synchronization frequency.  The subscriber unit then determines a value .gamma., which is proportional t o and .beta. and inversely proportional to .alpha.. The subscriber unit reference frequency is multiplied by .gamma. to achieve the frequency at whi ch the subscriber unit (14) transmits.

Abstract: The utility of the promoter/enhancer region (i.e. regulatory region) of the PSP94 gene in targeting expression of heterologous genes, to the prostate gland was analyzed. Three breeding lines (i.e., line A, line B line C) of the PSP-TGMAP (PSP94 gene driven transgenic mouse of adenocarcinoma of the prostate) model were established with constructs containing regulatory regions with or without additional exon/intron sequence of the PSP94 gene. These regulatory regions were operatively linked to the simian virus 40 (SV40) T antigen (Tag, including both the large T and small t antigens). Histopathology evaluation of tumor grade, transgene expression, tumor responsiveness to androgen deprivation and tumor metastatic potential were analyzed and reported herein. This study indicates that regulatory regions (i.e. the promoter/enhancer with exon/intron region) of the PSP94 gene efficiently target the expression of heterologous genes to prostate tissue. Furthermore, the PSP-TGMAP model provides a valuable tool for the analysis of prostate cancer development and for developing new gene therapy vector for the treatment of prostate cancer. Based on this study, mouse PSP94 promoter/enhancer (i.e., regulatory) region may be used in the generation of a "shuttle vector" fit for prostate targeting in both mouse CaP model and in human clinical trial.

Filed: 2001-12-17
Abstract: A plumbing fixture adapted to be installed from the top side of a sink deck through a sink deck opening includes a housing having a body portion which is adapted to extend through the sink deck opening and below the sink deck when mounted. The housing has a shoulder which is adapted to seat on the sink deck when mounted. There is a collar slidably movable on the body portion and of a size to pass through the sink deck opening. A threaded bore is in the collar and an unthreaded bore is in the housing shoulder, and a threaded member extends through these bores, with rotation of the threaded member from above the sink deck moving the collar axially along the housing body portion. Outwardly- biased yielding members are associated with the collar and extend outwardly therefrom such that when so extended the collar will not pass through the sink deck opening. The fixture is mounted to the sink deck by first compressing the outwardly extending yielding members to pass the body portion and collar through the sink deck opening from above the sink deck until the shoulder portion is seated on the sink deck and the yielding members have extended after passing through the sink deck opening. The threaded member is then rotated until the collar has moved axially along the body portion and is in contact with the underside of the sink deck.
