Title: Impact-identity elements
Inventor: GO GIOK DJIEN
IPC: B60R22/48
Filed: 2001-02-02
Abstract: Impact-identity elements in association with a method to prevent manipulation create a chain of tamperproof evidence for the non-use of seat belts in real-world accidents.  Consequently, the car-, train-, aeroplane manufacturer or the airline is saved lawsuits, compensatory damages and/or medical-expenses. Energy-absorbing impact-identity elements gradually absorb great mass inertia forces or great kinetic energy of the belted passengers at threshold values, lower than the injury-relevant threshold values and the tensile strength of seat belt, in order to enhance the survival chance and save costs associated with further use of the seat belts. Thanks to an innovative design of belt fittings, releasably attached to seat belts, outside the seats, all the impact-identity elements can easily be checked and replaced, when damaged, thus saving time and costs. Flight attendants and/or apprentices can easily exchange worn impact-identity elements with new ones or the impact-identity elements, set up for babies, with ones for obese people.

Abstract: In transportation means (jet propulsion boat 10) equipped with a liquid crystal display unit (liquid crystal device 71) displaying operation information, an ordinary movement of the transportation means is regarded as an ordinary state; and when a case where the need arises for abruptly reducing the speed of the transportation means or abruptly changing the direction of the transportation means, and the like are distinguished as a non-ordinary state, the liquid crystal display unit (liquid crystal device 71) has been caused to reverse a white-and-black display thereof when the transportation means shifts from the ordinary state to the non-ordinary state. It is possible to sensitively and directly notify the driver that the transportation means is in a non-ordinary state. As a result, it becomes easier to recognize that the transportation means is in a non-ordinary state.

Abstract: An input signal DT contains a segment synchronization signal compliant with the ATSC standard. A clock multiplication section 111 multiplies a clock CK. A switchable sampling section 112 selects a sample point from among a plurality of timing points that are defined by the multiplied clock, and samples the input signal DT at the selected sample point. Moreover, the switchable sampling section 112 switches sample points from one to another in a synchronization-unestablished state. Once the segment synchronization is established, a synchronization detection device may maintain a synchronization-established state until the field synchronization detection fails, or the synchronization detection device may output a synchronization detection signal after shifting it in the time direction based on a bit error rate RT of the input signal.

Inventor: SEGURA PEDRO R
IPC: E21B49/10
Filed: 2003-03-06
Abstract: The present invention is directed to methods and apparatus for using a formation tester to perform a pretest, in a formation having low permeability, by intermittently collecting a portion of fluid at a constant drawdown rate. The drawdown pressure is monitored until a maximum differential pressure is reached between the formation and the tester. Then the piston is stopped until the differential pressure increases to a set value, at which time the piston is restarted. The controlled intermittent operation of the piston continues until a set pretest volume is reached. The modulated drawdown allows for an accurate collection of pressure versus time data that is then used to calculate the formation pressure and permeability. The present invention also finds applicability in logging-while-drilling and measurement-while drilling applications where power conservation is critical.

Title: System for identifying common digital sequences
Inventor: MOULTON GREGORY HAGAN
IPC: G06F17/30
Filed: 2001-10-04
Abstract: A system and method for unorchestrated determination of data sequences using  "sticky byte" factoring to determine breakpoints in digital sequences such that common sequences can be identified. Sticky byte factoring provides an efficient method of dividing a data set into pieces that generally yields ne ar optimal commonality. This is effectuated by employing a rolling hashsum and,  in an exemplary embodiment disclosed herein, a threshold function to deterministically set divisions in a sequence of data. Both the rolling hash  and the threshold function are designed to require minimal computation. This  low overhead makes it possible to rapidly partition a data sequence for presentation to a factoring engine or other applications that prefer subsequent synchronization across the data set.

Abstract: This disclosed Finger and Toe Stimulation and Hand Massage Device consists of a flexible, extendible loop of plastic or rubber tubing or solid material, of about three-sights of an inch in diameter and from about six to the twelve inches in circumference, having a handle disposed along one part of its circumference. In use as a Finger Stimulation Device it is held with one hand by the handle and the loop of it opposite the handle is placed sequentially across each of the joints of the fingers of the opposite hand and then the hands are moved apart so as to apply repeated stretching pressure by means of the device, pulling straight away from each joint of each finger in turn, keeping the finger pointed straight at the handle to get the best results. If the user them self is stimulating their fingers, then the role of the hands are reversed so that all joints of each finger of both hands are similarly stimulated. Additionally the device may be doubled around the backs of the hands with the fingers interlaced to massage the backs of the hands.  With assistance, the device may be used in a similar way as a Toe Stimulation Device. The Figure shows an embodiment of my Finger and Toe Stimulation and Hand Massage Device.

Abstract: A method and system for normalizing optical spectra using a non-uniform segment normalization. A spectrum is obtained and is represented as a functi on of wavelength as an amplitude at each of a plurality of wavelengths. At leas t one segment of the spectrum is selected, each selected segment being bounded  by an upper wavelength and a lower wavelength. A normalization factor is computed as the sum of the areas for each of the selected segments. The spectrum is normalized by dividing at least one amplitude of the spectrum by  the normalization factor. Segments can be selected with different wavelength  ranges, that is, segments can be non-uniform. Test specimens can be categorized based on an analysis of normalized spectra. In particular, the specimen to be tested can be human cervical tissue, and the state of health of the tissue can be determined.
