Title: Multi-mode communication network with handset-selected channel assignments
Inventor: ZICKER ROBERT G
IPC: H04M1/72511
Filed: 1997-06-03
Granted: 2008-02-19
Abstract: A multi-mode communication network (12) accommodates piloted cellular operation and pilotless cordless operation using a multi-mode handset (18). A  common pool of channels (28) serves cellular and cordless operations. At least some channels from a cordless subset (32) of the pool of channels (28) are unused in cellular operations regardless of location. The handset (18) monitors forward portions of all cordless subset channels when the handset (18) is within the coverage area (16) of its cordless base station (22). Unused channels are indicated on a dormant channel list (70), which is passed to the handset's cordless base station (22) when the handset (18) registers for cordless operation. The cordless base station (22) makes an active channel list (62) based upon the dormant channel list (70). Cordless operation messages transmitted from either a handset (18) or cordless base station (22) use a channel selected from the active channel list (62).

Abstract: A coupler pivot pin and retention clip assembly for a railroad car coupler adapted to pivotally connect a knuckle of the railroad car coupler to a body of the railroad car coupler. The pivot pin assembly includes a pivot pin having an elongate shank having a head at one end and a groove formed in the shank at a second end. A circular retention clip member is adapted to be selectively retained within the groove and to the shank to prevent removal of the pivot pin from the coupler. The retention clip member includes a generally circular band having a respective tab extending generally radially outwardly from each end of the band. The band is resiliently flexible from a relaxed position, wherein the band is adapted to be retained in the groove, to an expanded position, wherein the band has an enlarged diameter allowing the band to be removed from the groove and the pivot pin so that the pivot pin may be removed from the coupler, by manually pressing the first and second tabs together.

Abstract: A crop harvesting header includes a reel mounted on a pair of forwardly extending arms carried on a header frame above a table and cutting knife. The reel is rotatable about a longitudinal axis and includes bats with fingers which pivot each about a respective bat axis so the angle of the fingers varies as the reel rotates. The angle of the fingers can be varied to increase and decrease the angle at the knife. The arms include a forward portion which is arranged at an angle to a main portion so as to be inclined downwardly and forwardly therefrom. As the reel supports on the arms is moved forwardly along the arms and engages onto the forward portion, the reel is moved downwardly and forwardly which simultaneously changes the angle to provide a more aggressive action as the reel is moved forwardly of the knife.

Filed: 2000-01-07
Granted: 2009-03-10
Abstract: A no base coat vehicle headlamp reflector can be improved with a plasma deposited layer of a siloxane material. The siloxane layer acts as an barrier layer formed directly on the vehicle reflector.

Title: Method and apparatus for encoding and decoding multiple audio channels at low bit rates
Inventor: FELLERS MATTHEW CONRAD
IPC: H04H20/88
Filed: 1998-06-19
Granted: 2008-09-02
Abstract: A split-band coding system combines multiple channels of input signals into various forms of composite signals and generates spatial-characteristic signals representing soundfield spatial characteristics in a plurality of frequency subbands. The spatial-characteristics signals may be generated in either or both of two forms. In a first form, the signal represents measures of signal levels for subband sig-nals from the input channels. In a second form, the signal represents one or more apparent directions for the soundfield. The type of the spatial-characteristics signal may be adapted dynamically in response to a variety of criteria including input signal characteristics.    Temporal smoothing and spectral smoothing of the spatial-characteristics signals may be applied in an encoder. Temporal smoothing and spec-tral smoothing may be applied to gain factors derived from the spatial-characteristics signals in a decoder.

Title: Non-invasive penile erection device
Inventor: VOLLRATH JIJI SECONG
IPC: A61F5/41
Filed: 1998-07-14
Granted: 2004-03-30
Abstract: The present invention relates to a non-invasive penile erection device (20) having a constrictor ring (30) designed to fit against the base of the male genital or penis, and a diaphragm seal (80) that forms a substantially airtight seal against the constrictor ring (30). The constrictor ring (30) is designed to comfortably, and securely fit the base of the penis. The substantially airtight seal (80) enables the pump (200) to produce vacuum pressures of over 17 inches of mercury. The diaphrag m seal (80) is designed to collapse around the constrictor ring (30), and remain on during sexual activity. The diaphragm seal (80) cooperates with the constrictor ring (30) to apply pressure to the surface of the penis. The placement of the constrictor ring (30), and the greater vacuum pressure tend to achieve and maintain a more natural erection.

Abstract: A cigarette (30) includes an ignition element (36) in contact with tobacco (40, 42), surrounded by a composite outer wrapper (38).  The outer wrapper (38) is impervious to oxygen causing the tobacco (40, 42) to extinguish between puffs. The ignition element (36), however, has a longer static bum time than the tobacco (40, 42) and remains smoldering between puffs. Upon a subsequent puff, the smoldering ignition element (36) reignites the tobacco (40, 42). One or more initially occluded perforations (34) in the outer layer (38) maintain the uniformity in combustion of the tobacco (40, 42) and the ignition element (36).

Abstract: An embedded-type light (1) has a base (3) of a bottomed cylinder embedded in a PC pavement (2) and a light body (5) supported at the top of the base (3) and emitting light outside the pavement surface.  Projections (6) are provided on the outer surface of the base (3) so as to bear the load exerted downward on the light body (5) by the PC pavement (2) around the base (3). Thus, the load does not concentrate on the lower portion of the base (3). To alleviate the lack of stress in the PC  pavement (2) around the lower portion of the base (3), a cushioning material (7) is provided around the lower edge of the base (3). As a result, the decrease in strength of the PC pavement (2) around the lower portion of the base (3) is suppressed. Therefore the PC pavement around the lower portion of the base is prevented from turning brittle and a hollow in the PC pavement is prevented even if a very heavy load such as an airplane is exerted.
