Title: Multi-sensor explosive detection system
Inventor: GOZANI TSAHI
IPC: G01V5/00
Filed: 1990-06-15
Granted: 2001-08-21
Abstract: A nuclear detection system (100) and method efficiently detects contraband, such as explosives, in checked airline baggage or other ob-jects with a high probability of detec-tion (PD) and a low probability of false alarms (PFD). The detection sys-tem includes a source of thermal neu-trons (102, 130); an array of gamma ray detectors (114, 144); a neutron de-tector (146); means for irradiating the object (136, 142,144) being examined to neutrons from the neutron source which neutrons interact with the at-omic nuclei of one more specific elements, e.g., nitrogen, chlorine, or hydrogen present within the object so as to cause elemental-specific gamma rays to be emitted and processing means (116, 154). Elemental-specific gamma rays detect-ed and counted by the gamma ray detectors and processing means allow the approximate origin of the gamma rays within the ob-ject to be determined, thereby providing a rough measure of the density distribution of these specific elements within the object. Neutrons that pass through the object without substantially interacting with atomic nuclei are detected by the neutron detector, thereby providing an image of the atomic density distribution of the object similar to conventional neutron radiography. One em-bodiment of the invention includes an artificial neural system (ANS) for analyzing the recorded gamma rays and efficiently dis-criminating between objects carrying explosives and objects not carrying explosives. Another embodiment utilizes a spectral correlation method (SCM) to remove undesirable background noise from the spectrum of detected gamma rays. Still another em-bodiment uses an X-ray system ( 150) to generate an electron density image of the object being investigated, which electron densi-ty image helps confirm the presence of explosives within the object.

Title: Method for determining electrical energy consumption
Inventor: BULLOCK DONALD F
IPC: G01R21/133
Filed: 1992-03-12
Granted: 2001-01-02
Abstract: A method of operating a meter to perform the steps of generating a measure of real energy consumed, generating a measure of reactive energy consumed, and generating, from the real energy and reactive energy measures, a measure of apparent energy consumed.      In one embodiment, the real energy and reactive energy measures are provided as integer quantity inputs. Particularly, assume S = kVAh, P = kWh, Q = kVARh, and R = Residue. Respective registers store values of P, [2P + 1], Q, [2Q + 1], and the sum [P2 + Q2]. Initially, the P, Q, and [P2 + Q2] registers are set to zero, while the [2P + 1] and [2Q + 1] registers are initialized to 1. At the arrival of a P pulse, the value in the [2P +1] register is added to the [P2 + Q2] register, then the P register is incremented by 1 and the [2P + 1] register is incremented by 2. Exactly the same steps are carried out subsequent to receipt of a Q pulse.      A set of registers also is used to store the S and [2S + 1] data, and generation of the S pulses is determined as follows. After arrival of either a P or Q pulse, a trial subtraction of [2S + 1] is made from the [P2 + Q2] register. If the subtraction does not cause an underflow, an S pulse is generated, the S register is incremented by 1, and the [2S + 1] register is incremented by 2. If the subtraction causes an underflow, the (P2 + Q2] register is reset to its previous value, the other registers are not incremented, and no S pulse is generated.

Title: Optical recording medium driving apparatus
Inventor: MATOBA HIROTSUGU
IPC: G11B7/085
Filed: 1992-07-27
Granted: 1996-06-25
Abstract: An optical recording medium driving apparatus has the first high-pass filter for outputting a low frequency component removed signal by removing a low frequency component from a reproduction signal varying depending on a reflected light beam from the optical recording medium. The low frequency component removed signal changes due to transient response just after an access operation starts. Zero voltage is inputted to the second high-pass filter during a tracking operation while a voltage having a negative polarity which is substantially the same amplitude as the AC component of the low frequency component removed signal is inputted to the second high-pass filter.   The first high-pass filter has the same time constant as the second high-pass filter.   Just after the access operation starts,  the negative voltage has the same transient response as the output of the first high-pass filter.   The output of the first high-pass filter is compared to the output of the second high-pass filter in order to have a binary signal of the binary logic condition.   A land is discriminated from a groove according to the binary signal, thereby enabling to access a target track in accuracy.
