Title: Wide area trunked channel busy override
Inventor: FELDERMAN WILLIAM A
IPC: H04W72/04
Filed: 1991-03-20
Granted: 1995-03-14
Abstract: A typical multi-site trunked communication system (100) comprises communication units (110-116) that are arranged into talk groups, communication resources (106-109) distributed among communication sites, (102-105) and a communication resource allocator (101). In such a system, a methodology is incorporated that allows communication units (110-116) to override communication site busy conditions, where the communication site busy conditions prohibits placement of group calls until all communication sites (102-105) have an available communication resource (106-109). The communication site busy condition may be overridden by a communication unit (110-116) by initiating a busy override signal. Once the busy override signal is initiated, the communication resource allocator (101) allocates, in each site (102-105), a communication resource (106-109) to the communication group of the requesting communication unit (110-116).

Title: Electromagnetic attachment mechanism
Inventor: MONFORD LEO G JR
IPC: B25J19/00

Granted: 1995-10-17
Abstract: An electromagnetic attachment mechanism for use as an end effector of a remote manipulator system.  A pair of electromagnets 15A,15B, each with a U-shaped magnetic core with a pull-in coil 34 and two holding coils 35,36 are mounted by a spring suspension system 38,47 on a base plate 25 of the mechanism housing 30 with end pole pieces 21,22 adapted to move through openings in the base plate when the attractive force of the electromagnets is exerted on a strike plate 65 of a grapple fixture 20 affixed to a target object 14.  The pole pieces are spaced by an air gap from the strike plate when the mechanism first contacts the grapple fixture. An individual control circuit and power source is provided for the pull-in coil and one holding coil of each electro-magnet.  A back-up control circuit connected to the two power sources and a third power source is provided for the remaining holding coils. When energized, the pull-in coils overcome the suspension system and air gap and are automati-cally de-energized when the pole pieces move to grapple and impose a preload force across the grapple interface.  A bat-tery back-up 89A,89B is a redundant power source for each electromagnet in each individual control circuit and is auto-matically connected upon failure of the primary power source. A centerline mounted camera 31 and video monitor 70 are used in cooperation with a target pattern 19 on the reflective surface 67 of the strike plate to effect targeting and align-ment.

Abstract: A television system comprises a first input terminal (20) for providing a composite video (CSCC) signal or a separated luminance (SCC) signal, and a second input terminal (15) for providing a separated chrominance (C) signal. A change-over switch (11) has a first input (a) coupled to the first input terminal (20) through a path including a color subcarrier filter (9), a second input (b) coupled to the second input terminal (15) through a path not including the color subcarrier filter (9), and an output (c) coupled to the input (d) of a color decoder (8). The change-over switch couples the input (d) of the color decoder (8) to the first input terminal (20) in a first position (a), and couples the input (d) of the color decoder (8) to the second input terminal (15) in a second position (b). A subcarrier detector (CK) is coupled to the output (c) of the change-over switch (11) for detecting the presence of absence of a color subcarrier. A control unit initially causes the change-over switch (11) to be in the first position (a) and thereafter causes said change-over switch (11) to remain in the first position (a) if a color subcarrier is present at the output (c) of the change-over switch (11), but causes the change-over switch (11) to be in the second position (b) if a color subcarrier is not present. Once the change-over switch (11) is in the second position (b), the control unit (1) causes said change-over switch (11) to be switched back to said first position (a) from said second position (b) if a color subcarrier is still not present.

Granted: 1996-10-22
Abstract: A log chipper is provided for allowing a lower horsepower rated motor to drive the chipper.      Peak power demand is reduced by cutting shorter chips from large diameter logs, while the length of chips cut from logs of small and medium diameter continues to be of standard specified length, the length of chips cut from large diameter logs only being shortened. The feed rate for large diameter logs is reduced and will therefore result in a reduction of peak power demand achieved by the use of large diameter log positioning means. A first version of the large diameter log positioning means involves the placement of a raised platform on the wear plate where the outer perimeter of the large diameter log would otherwise contact the wear plate. A second version of the positioning means involves raising the heel of the knife clamp at a point where a portion of the outer perimeter of a large diameter log contacts the heel of the clamp. A third version of the positioning means involves grinding an outer face of the knife assembly where a portion of the outer perimeter of a large diameter log contacts the knife assembly. The special grind provides a unique relief angle to cause a shorter chip to be cut from the large diameter log. A final version of the large diameter log positioning means involves the inward adjustment of one of a series of sectional knife assemblies at the point where a portion of the outer perimeter of a large diameter log contacts the knife assembly.
