Abstract: A non-contacting transaction system as described which includes a hand-held device which contains information unique to the user and which, when actuated by the user, generates a wireless signal which is picked up by a receiver. In a preferred arrangement, the transmitter contains the user's code and has a keypad for the user to insert a personal identification number (PIN) code. The receiver is coupled via a transmission line to a local system where the user's code and PIN number and details of the purchase, received from the vendor, are registered against the user's number so that billing can be carried out subsequently. The receiver can include a means for checking and for rectifying the correctness of the code and PIN number prior to transmitting the data via the modem to the central system. Various embodiments of the invention are described; for example, the device is flexible and the PIN number could be required for all transactions to minimise fraud. Each transmitter may be provided with a terminal to allow an input to the memory for changing details of the user's account and charge number. To prove ownership of the transmitter, the owner's name, telephone number, car registration number, etc. may also be fused in the memory along with the credit card number. This information would be displayed only to the vendor who could ask the person who was using the transmitter to identify himself by name, PIN, telephone number or car registration as proof of identity.

Title: Dynamic compression-rate selection arrangement
Inventor: MOHLER DAVID S
IPC: H04M1/65
Filed: 1995-02-06
Granted: 1999-09-07
Abstract: A signal compression-selection arrangement dynamically trades off signal storage capacity against signal quality, by sacrificing capacity in favor of signal quality whenever capacity is plentiful and sacrificing quality in favor of capacity whenever capacity is scarce. In a messaging system, the arrangement monitors the amount of storage that is presently free and available for storing new messages, either on a system-wide or per-mailbox basis, and automatically selects a higher compression rate than a presently-applied compression rate to be applied to newly-received messages as the amount of free storage falls below each predetermined threshold. Storage capacity may be freed up by recompressing at the new, higher, compression rate those stored messages that were previously compressed at a lower compression rate.

Abstract: The present invention relates to a disk drive recording apparatus and more particularly to a method for optimizing performance of a read channel in a disk drive recording apparatus by using an error rate. The method for optimizing performance of a read channel in a disk driving recording apparatus having a programmable low-pass filter and a control device for controlling apparatus operation includes the steps of initially assigning a filtering characteristic to the programmable low-pass filter as a predetermined initial bandwidth value via the control device; detecting and evaluating data written on a first predetermined track of a disk to calculate a first data detection error rate by the control device; comparing a reference error rate with the first data detection error rate; setting the filtering characteristic of the low-pass filter to a bandwidth indicating a lowest error rate by varying the bandwidth of the programmable low-pass filter when the first data detection error rate is greater than a reference error rate; thereafter, detecting data written on a second predetermined track of the disk to calculate a second data detection error rate by the control device; comparing the reference error rate with the second data detection error rate; outputting an error state signal indicating that the disk drive recording apparatus is in a poor state when the second data detection error rate is greater than the reference error rate; and setting a currently set bandwidth as a final set value and completing an optimization process when any one of the first and second data detection error rates is below the reference error rate.

Abstract: A device and method for monitoring the angular displacement of a rotating shaft provides an ultrasonic transceiver reflecting pulses off of a reflecting edge of a vane of a rotor affixed to the shaft. The reflecting edge is configured in the profile of an involute curve so that changes in the time delay between transmission and reception of each reflected pulse, which correspond to changes in the distance between the transceiver and the reflecting edge, are linearly related to changes in the angular displacement of the shaft, and arranged such that the reflecting edge is normal to the probe axis so that the energy is reflected back to the probe. A circular disc may be associated with the vane to provide a reference reflected pulse, which eliminates errors which might occur due to wobbling of the shaft.

Title: Interaction of routing features in a telephone system
Inventor: ZAVE PAMELA
IPC: H04M3/42
Filed: 1996-07-30
Granted: 1999-12-21
Abstract: Techniques for analyzing interactions of call routing features in a telephone system and implementing the features. Analysis and implementations are based on the recognition that a customer intends a call routing feature to apply to a telephone number which represents either a subscriber to which a call should be routed or a telephone number to which a call should be routed. From this recognition flow two classes of routing features: telephone features, which apply to telephone numbers representing telephones, and subscriber features, which apply to telephone numbers representing subscribers. How a given feature interacts with other routing features depends upon which of of the two classes it belongs to. Routing features may be implemented by keeping track of a telephone number which functions as a subscriber pointer and of one which functions as a telephone pointer and recursively invoking functions for subscriber and telephone features. The recursive invocations permit forwarding chains of any length. The techniques have also led to the development of a number of new call forwarding and call blocking features.

Abstract: A multiple coring bit tool and method for taking multiple core samples of a formation traversed by a borehole in one well logging run. In this tool, multiple coring bits are used to cut the core samples. One bit is used to cut each sample. Once the core sample has been taken, the cutting bit containing the core sample is stored. For the next core, a new cutting bit is used and that cutting bit contains that core sample once the coring process is completed. Multiple cutting bits are held in two or more chambers prior to use in the coring process. The bits in one chamber are used to cut core samples from formation location above a certain hardness and the bits in the second chamber are used to cut cores in formations below a certain harness. Two other chambers are incorporated in the tool for storage of the cutting bits once the core sample has been obtained. The sequence of the sample is tracked thereby permitting the identification of any core sample and the location in the formation from which the core sample was taken.
