Title: Signal line increased current kicker terminator apparatus
Inventor: SAMELA FRANCIS M
IPC: G06F13/40
Filed: 1993-04-26
Abstract: A terminator apparatus used with a SCSI buss line 14a for controlling the voltage level of a notch occurring in data and/or control signals (REQ, ACK) transferred on the buss line includes a termination network 112, a current switching device 114, and a programmed monitoring circuit 116. The termination network generates a first current. The current switching device generates a second current. The monitoring circuit controls a programmed length of time that the second current is generated. The current switching device is responsive to the monitoring circuit for disconnecting the second current when the programmed length of time has been exceeded. The second current serves to raise the voltage level of the notch occurring in the signal lines when they are deasserted so as to prevent erroneous data from being transferred. <IMAGE>

Title: Method of guiding golf carts
Inventor: KOSEKI MASAMORI
IPC: A63B55/60
Filed: 1993-07-26
Abstract: On the basis of a cart driving guide method which moves forward a cart (4) exactly following marker lines (2) when guide member detection means of the cart (4) detects the marker lines (2) consisting of cart guide members, the method of the invention automatically operates each cart (4) so that different carts run on different passages. Driving changeover detectors (5) are laid down at arbitrary positions of the marker lines (2) or in the proximity of the marker lines (2). When the driving changeover detectors are sensed, a golf cart (4) is allowed to drive by a distance (L), which is different from cart to cart, in such a manner as to profile a marker line (2) after this detection, and after this distance is covered, the cart is moved forward with its steering angle changed to a predetermined direction. After the cart moves forward by a predetermined distance, a steering angle is changed to the opposite direction and the cart is moved forward. <IMAGE>
Patent GB-2274189-A (GB)
Title: Alarm systems
Inventor: PHARAOH PETER LEONARD GEORGE
IPC: G08B29/18
Filed: 1994-01-10
Abstract: An alarm system has detectors each with an associated local indicator and all capable of triggering a remote alarm. A short lived disturbance at any detector, below a set threshold, will merely activate the local indicator, and it may only do that if it lasts for several seconds. But should the disturbance exceed a given period and/or a set threshold, the remote alarm will be activated. A remote monitoring station may be silently advised of the state of the detectors, and generate a standby signal before any disturbance reaches a level to activate the alarm.

Title: Security device for steering wheel of a motor vehicle
Inventor: HAQUE ZIA
IPC: B60R25/022
Filed: 1994-10-05
Abstract: The security device comprises a steering wheel in 2 parts. When mounted the wheel rotates freely without engaging the rotatable member. The movement is controlled by a key in the centre of the device, a turn of this key engages the rotatable member. Once the wheel is disengaged any freewheeling movement of the wheel triggers an alarm switch activating also a flashing light to illuminate any intruder's face. The invention also allows a car horn to be operated via touch controls and also incorporates special lock nuts to prevent unauthorised removal of the security device. The outer part of the steering wheel is secured to the centre via two central shafts, connected to two way springs placed in the shaft. When sudden and heavy force is applied to the wheel, the impact is absorbed by the springs. <IMAGE>

At least one verical fin (100) is upstanding from the shoulder, preventing upward deformation of the lower skirt portion (74). The lower skirt portion (74) has at least one internal ratchet tooth (81) and a line of weakness (87) through the outer skirt portion and the shoulder. The lower portion skirt has a tear tab (86) which, when pulled, fractures the lower skirt at the frangible section (76). <IMAGE>

Title: Error detection system
Inventor: GOULD ADAM F
IPC: H03M13/00
Filed: 1991-09-03
Abstract: An error detection system 200 for a discrete receiver indicates bad frames of binary information signals 206 which contain distorted bits in densities so great as to cause a decoder 212 to generate an incorrect, decoded signal. A soft decision signal decoded by a convolutional decoder 212 is re-encoded by an encoder 224, and the re-encoded signal 230 is compared 256 with the signal 206 - 248 received by the receiver. When portions of the re-encoded signal 230 differ too greatly from the actual, received signal 206 - 248, a bad frame indication 286 is generated. <IMAGE>

Title: Integrated circuit packages
Inventor: ARMSTRONG DAVID YORKE
IPC: H01L25/10
Filed: 1995-04-24
Abstract: An integrated circuit memory package comprises a plurality of integrated circuit assemblies (62) attached to a base (63), each assembly (62) comprises a flat substrate (31) having a plurality of contact terminals (33) arranged along a lower edge thereof and integrated circuit memory devices attached to respective opposite sides thereof (10,R,105). The assemblies (62) are bonded to each other prior to attachment to the base (63), such that their respective lower edges are arranged in a plane which extends perpendicular to the substrates (31). The contact terminals (33) are connected to respective contact terminals (63) on the upper surface of the base (64) by means of a conductive butt joint. A good connection is formed between the substrates (31) and the base (64) because bonding the assemblies (62) together helps to ensure that the contact terminals (33) on each substrate (31) are aligned correctly with the corresponding terminals (63) on the base (64).

IPC: G03G15/16
Filed: 1995-04-26
Abstract: An image forming device incorporated in an image forming apparatus and capable of cleaning a residual toner on a transfer belt. A transfer belt transports a sheet to a nip portion of an image carrier and the transfer belt. A transfer bias current It1 is applied to the transfer belt 8 from a power source 18 so that a toner image on an image carrier 2 is transferred to a sheet P at a nip portion B. A cleaning bias current It2 is applied to a cleaning bias roller 16 or brush (22, Fig 3) which is held in contact with the transfer belt so as to remove residual toner and paper particles from the transfer belt. An electric current Ir is returned from the transfer belt to a transfer control board 20 which is also connected to the power source 18. The transfer control board controls the current It1 or It2 to satisfy an equation (It1 + It2) - Ir = IOUT where IOUT is constant. Separate power sources 18, (26, Fig 11) may be provided to supply the currents It1, It2, each source being connected to control board 20. Cleaning roller 16 may be connected to power source 18 via a resistor (23, Fig 4; 24, Fig 9) or a diode (25, Fig 10). <IMAGE>
