PCT No. PCT/JP96/03778 Sec. 371 Date Apr. 17, 1998 Sec. 102(e) Date Apr. 17, 1998 PCT Filed Dec. 25, 1996 PCT Pub. No. WO98/11456 PCT Pub. Date Mar. 19, 1998This invention provides a contaminant-detecting apparatus having high selectivity and high sensitivity against a contaminant. A product (1) is conveyed to a point where it is irradiated by x-rays from source (3). An x-ray detector (4), having a predetermined detection unit width in a direction perpendicularly intersecting the conveying direction, then detects the x-rays transmitted through the product. A storage unit (5) stores a two-dimensional distribution of x-ray intensity detected by the x-ray detector as a transmission image in units of pixels. An average calculation unit (7) performs a sum-or-product operation of a kernel, which is equal to or larger than 7x7 pixels, (9x9 or 11x11), and equal to or smaller than (a pixel count corresponding to +E,fra 1/2+EE the predetermined x-ray detection unit width)x(pixel count corresponding to +E,fra 1/2+EE the predetermined x-ray detection unit width), and includes a target pixel, in units of pixels of the transmission image stored in the storage unit by using a predetermined coefficient matrix, thereby calculating the weighted average over the kernel. A difference calculation unit (8) calculates the difference between the x-ray intensity of the target pixel of the transmission image stored in the storage unit and the weighted average over the kernel of the target pixel which is calculated by the difference calculation unit. A determination unit (9) compares the difference calculated by the difference calculation unit with predetermined criteria, thereby determining presence/absence of a contaminant in the product to be tested.

A first ignition cylinder that performs ignition first is set based on an engine stop position in automatic start. Existence/nonexistence of a misfire in the first ignition cylinder is determined based on whether a difference ΔNe between engine rotation speed at a predetermined crank angle in an interval from timing immediately before the ignition to timing immediately after the ignition of the first ignition cylinder (e.g., at TDC of first ignition cylinder) and engine rotation speed at a predetermined crank angle before ignition of a second ignition cylinder (e.g., at TDC of second ignition cylinder) is equal to or smaller than a predetermined misfire determination threshold value Nef. When misfire time number of the first ignition cylinder exceeds a predetermined value, fuel supply to the first ignition cylinder is prohibited and the automatic start is started from the second ignition cylinder.

A controller determines, in response to a position coordinate from an X/Y interferometer, which algorism should be used for current inspection, and controls a connection status of a switch to store a reference image corresponding thereto in an image memory. The reference image is one of an image of a sample surface obtained by an image data acquisition unit, an image provided from a cell reference image generation unit, and an image provided from a CAD data reference image generation unit. The controller further controls a connection status of a second switch to provide the reference image associated with the current inspection algorism to an image comparator, where the provided reference image is compared with a currently obtained image. On the basis of a result of the comparison, a defect determination unit determines the presence/absence of a defect. Therefore, an utilization efficiency of a defect inspection apparatus which is capable of performing a plurality of defect inspection algorism, can be improved.

A conversation detection apparatus uses a head-mounted microphone array to accurately determine whether a speaker in front is a conversing person or not. A conversation detection apparatus (100) includes a self-speech detection section (102) that detects a speech of a wearer of a microphone array (101), a front speech detection section (103) that detects a speech of a speaker in front of the microphone array wearer as a speech in front direction, a side speech detection section (104) that detects a speech of a speaker residing at at least one of right and left of the wearer as a side speech, a side direction conversation establishment degree deriving section (105) that calculates a conversation establishment degree between the speech of the wearer and the side speech, based on detection results of the speech of the wearer and the side speech, a front direction conversation detection section (106) that determines presence/absence of conversation in front direction based on a detection result of the front speech and a calculation result of the side direction conversation establishment degree, and an output sound control section (107) that controls directivity of speech heard by the hearing aid wearer, based on the determined presence/absence of conversation in front direction.

The presence or absence of objects is determined by interrogating or exciting transponders coupled to the objects using pulsed wide band frequency signals. Interrogation is broken down into a number of subsample scan cycles each having interrogation cycles a start time forward in time by a fraction of a period of an expected transponder response signal. Ambient or background noise is evaluated and a threshold adjusted based on the level of noise. Adjustment may be based on multiple noise measurements or samples. Noise detection may be limited, with emphasis placed on interrogation to increase the signal to noise ratio. Matched filtering may be employed. Presence/absence determination may take into account frequency and/or Q value to limit false detections. Appropriate acts may be taken if detected noise is out of defined limits of operation, for example shutting down interrogation and/or providing an appropriate indication.

A plug of a power cord of a block heater which is mounted to a cylinder block of an engine, is connected to a household power receptacle to energize the block heater during an engine stoppage in cold climate. Thus, an engine coolant is kept warm to prevent freeze. Existence/nonexistence of the energization to the block heater during the engine stoppage is determined based on a behavior of coolant temperature or a behavior of engine rotation speed immediately after an engine start. If it is determined that the energization to the block heater exists, abnormality diagnosis of a cooling system is prohibited or a condition for the abnormality diagnosis is corrected and estimation coolant temperature is corrected.

An integral detection and identification system for detecting and identifying an object includes an identification transponder and a presence/absence transponder. The identification transponder includes a first inductive winding wound about a core and electrically coupled to an integrated circuit to transmit an identification signal in response to receipt of an interrogation signal in a first frequency range. The identification signal encodes an identifier stored by the integrated circuit. The presence/absence transponder includes a resonant inductive/capacitive tank circuit having at least a second inductive winding wound about a core and electrically coupled to a capacitor to transmit a presence/absence signal in response to an interrogation signal in a second frequency range. The presence/absence response signal lacks unique identifying information and is physically coupled to the identification transponder to form an integral detection and identification transponder that can selectively be attached to the object.

A configuration for a cryo-catheter which optimizes both the catheter's outer diameter and the size of the catheter's internal refrigerant flow path is described. Specifically, the inner dimensions of the cryo-catheter are configured to accommodate a pre-selected flow of refrigerant into the catheter's distal tip, and a return flow of refrigerant from the distal tip. The return flow is established in the void spaces between a refrigerant supply line and the inner wall of the catheter body. The available void space varies along the catheter length and depends on the presence/absence of various catheter accessories (i.e. pull wires, pressure tubes, etc.) which typically only extend through a portion of the catheter length. The disclosed configuration ensures that the cryo-catheter does not operate in a refrigerant limited condition, maintains the refrigerant as a liquid in the supply tube, and maintains the return line pressure at about 1 atmosphere.

A computer system is disclosed herein that surveys numerous legal documents which memorialize business or legal transactions and then determines common provisions in such documents. The forms of these “core provisions” are then stored in a knowledge base of the system. The system then allows attorney users to apply the system to analyze unsurveyed documents and use the knowledge base to recognize the core provisions that are most similar to the text of these unsurveyed documents. The user can then edit these unsurveyed documents in a rapid accurate fashion by automated means to revise text to match these core provisions. Document editing functionality is also present, along with means to use correlations to determine the likelihood of the presence/absence of specific provisions and the presence/absence of various particular documents in groups of documents used to memorialize certain types of transactions.
