Abstract: A suspension system with a contained force system concentrates loads in the suspension geometry control elements. This permits elimination of large, heavy load bearing structures in remote areas of the vehicle, use of a compact, modular structure, and combination of suspension geometry control and spring/damping in one unit. The modular suspension system for a wheeled vehicle comprises a wheel and hub assembly, a relatively heavier vehicle body, an interposed energy storage medium, and means to releasably store energy in the medium to any predetermined degree at any relative position between the wheel and hub assembly and the vehicle body upon relative movement between them.

Granted: 2000-12-12
Abstract: An attachment member arranged to be secured to a surface of a hard receiving material by an explosive powder charge operated setting tool is formed of a fastening element, such as a nail, and a prestressing element.  The prestressing element assures a sound attachment by bridging differences in the depth to which the nail is driven.  To increase its surface contacting the surface of the hard receiving material, the prestressing element is laterally enclosed at least in part by a plastics material part so that the pressure of the attachment member in contact with the receiving material and the danger of tilting of the setting tool relative to the receiving material are reduced.  Further, a recess is formed in the plastics material part to improve guidance between the prestressing element and a bolt guide of the setting tool.

Title: System and method for transmitting compressed data or pre-compressed data based on a preset compression ratio
Inventor: KAWASHIMA TETSUJI
IPC: G11B20/10
Filed: 1995-04-21
Granted: 2006-07-11
Abstract: A difference/compression ratio calculating means 76 in a data processing means 71 of a data transmitting apparatus according to the present invention calculates an actual difference and an actual compression ratio based on the data length of pre-compression data received from a data source 2 through pre-compression data receiving means 74 and the data length of compressed data outputted from a data compression circuit 67. If the actual difference is equal to or greater than a preset difference a and the actual compression ratio is equal to and greater than a preset compression ratio .beta., then the compressed data is transmitted to a data destination 3 through a transfer request data output means 79. Otherwise, the pre-compression data is transmitted to the data destination 3. With this arrangement, it is possible to prevent a phenomenon in which the size of compressed data which occupies a storage area in the data destination 3 is substantially the same as the size of uncompressed data which occupies the storage area, and also to avoid wasteful data expansion in the data destination 3.

Abstract: A  stair-like  log feeder having a movable drive module and a movable driven unit cooperating with one-another for unscrambling logs from a pile of logs and for moving the singularized logs upwardly along an inclined plane in a successive series of displacements.  The log feeder comprises a support frame having support rollers for slidably supporting the drive module and the drive unit. A cyclic actuator is connected to the drive module by  a  link  arm,  for  moving  the  drive  module  in  an alternating up and down movement along  the  inclined plane.   A first pair of rack gears is affixed to the drive module, and a second pair of rack gears is affixed to the driven unit.   A pair of gears is mounted on a transverse  shaft  which  is  pivotally  affixed  to  the support frame.   The pair of gears is engaged with the first and second rack gears for supporting both the drive module and the driven unit in a pendulum mode about the transverse shaft, and for converting a movement of the drive module  into an  equal,  opposite and concurrent displacement of the driven unit.  Each step of the drive module has a riser portion forming an angle of between about 3° and about 6° with the inclined plane.  Similarly each notch of the driven unit has a longitudinal edge forming an angle of between about 5° and about 8° with the inclined plane.

Abstract: An RF device (12), such as an amplifier, is tested by applying a digitally-modulated RF stimulus signal, having a known magnilude and phase angle, to the device from a stimulus generator (13) to cause the device to generate a response signal. The response signal of the device is down-converted and digitized by a receiver (18), that includes a mixer (20) and local oscillator (21), prior to establishing the magnitude and phase angle of the respsonse signal. The magnitude and phase angle of the digitized, down-converted response signal are compared to the magnitude and phase angle, respectively, of the digitally-modulated stimulus signal to yield transfer functions indicative of the operation of the device.

Abstract: A system, method and apparatus for Video-on-demand (VOD) satisfying the desire of 'surfers'. The process entails a server operating in a standard Near-Video-on-demand (NVOD) mode, whereby it repeatedly transmits multiple copies of each program on separate channels. Each copy is delayed by a staggeredtime interval. The server also repeatedly transmits a beginning portion of each NVOD program of a duration up to the staggered time interval. The invention provides a way to fulfill a VOD user requests asynchronous with the start of a NVOD transmission but which still makes primary use of the NVOD transmission for thatrequestor. The invention further advantageously provides fixed asset utilization in a predictable manner.

Title: Adaptable coin mechanism
Inventor: FLETCHER PAUL R
IPC: G07F5/24
Filed: 1996-09-20
Granted: 2010-03-16
Abstract: A coin mechanism has one or more coin tubes for storing, respectively, coins of one or more denominations, a dispenser for controlling the dispensing of coins from the coin tubes, and a coin mechanism controller suitable for connection to a controller in an automatic transaction system so as to receive change dispense signals from the automatic transaction system controller indicating the form of dispensing change to a customer. The coin mechanism controller, when connected to the automatic transaction system controller, serves as an interface between the automatic transaction system controller and the dispenser, and is programmed to re-determine the form of paying out the change, for example, by taking into account the distribution and denominations of the coins in the coin tubes. The arrangement of coin tubes in a coin tube cassette for use with the coin mechanism can be identified by entering a code on a keypad associated with the coin mechanism.
