Abstract: During the occurrence of an incoming call to a portable handset within an in building telephone system, a method is disclosed for providing additional information about the calling party, beyond simply their name or number, to a display on the handset. The name or number of the calling party is extracted by a central switching controller and is used as a reference in the look up of additional calling party attributes from a database located within a personal computer connected to the central switching controller. If the name or number of the calling party is found in the database, a data session is started between the called handset and the database. Following the starting of the data session, the first attribute in the database for the calling party is written to the display of the called handset and additional attributes are offered to the user. The incoming voice call is also offered to the display and a call acceptance signal from the called handset results in the establishing of a voice communication connection between the handset and the calling party. The offering of additional attributes for the calling party continues after the establishing of the voice communication connection between the called handset and the calling party.

Abstract: An improved infra-red lens array for use in a passive infra-red intrusion sensor, which maintains high detection capability for intruders moving in the middle and near field, and yet discriminates well between the movement of intruders and of pets in the near field. The upper part of the lens array is composed of at least one row containing convex lenses, operative to focus the far and middle field radiation of the area to be protected onto the detector of the sensor. The lower part of the array has at least one row containing cylindrical lenses, with their axes of symmetry aligned vertically, operative to focus infra-red radiation from the middle and near fields onto the detector. Each cylindrical lens focuses a vertical curtain of the protected area onto the infra-red detector. In order to ensure reduced sensor sensitivity close to the floor of the protected area, so as to provide pet movement discrimination, the cylindrical lenses are provided with spatially selective attenuation, so as to reduce their transmission factor as a function of the angle between the sensor and points on the floor.

Title: Method and apparatus for object detection and background removal
Inventor: SAKAMOTO SHIZUO
IPC: G06K9/00
Filed: 1998-10-01
Granted: 2002-08-27
Abstract: A method and apparatus is provided for object detection and background removal, and also storage media for storing a program which enables automatic detection of an object minutely and with high precision for obtaining an outline. A sectional image statistic calculation measure calculates a mean value and standard deviation of characteristic value of brightness of the sectional image, with the input image being subjected to division processing into sectional image. A  background sectional image selection measure causes a sectional image whose standard deviation is the smallest value in the sectional images to be taken as the sectional image with a high probability of including only the background. A background statistic estimation measure investigates the sectional image, including only the background, and another sectional image under the relationship between the mean value and the standard deviation. This investigation is implemented in terms of whole sectional images, a threshold generation object detection and background removal measure discriminates the background and the detected target object based on predetermined calculation procedure. A second threshold is in use, and is obtained in such a way that the standard deviation multiplied by the constant number given beforehand from the mean value is added thereto.

Abstract: This rebar chair has a body with four legs between which there are defined two intersecting passages for simultaneously receiving the intersecting portions of two rebars normal to each other. The rebars are suspended by a fastening wire or supported by an auxiliary chair below said body. The legs forming one of the passages have a uniform spacing and are adapted to closely straddle the rebar extending through the same. The chair is positively located and stabilized by the intersecting rebars. A saddle is formed on the top of the body for simultaneously supporting a third rebar. The spacing between the faces of the legs forming a first passage is uniform from the body to the free ends of the legs while the spacing between the faces of the legs forming the other right angle passage increases from the body to the free ends of the legs in such a manner that depending on the orientation of the chair with respect to the rebars the same can be positioned at two adjusted distances from the bottom of the concrete form.      The legs of the second passage flare downwardly so that their spacing progressively increases from the body to the free ends from a spacing smaller than to a spacing greater than the uniform spacing between the legs of the first passage.

Abstract: A pneumatic nailer having a safety mechanism that reduces accidental discharge of nailer is provided. The nailer includes a hollow main body housing having a main pressure chamber in pneumatic communication with a main valve housing. Pressurized gas is injected into main pressure chamber, and a metering hole between the main chamber and valve assembly allows gas pressure to equalize between the main chamber and the valve housing. A safety trigger and safety valve are in pneumatic communication with the pressurized valve housing. A ram cap positioned over the top portion of the valve assembly is struck, moving the main valve assembly downward, with unseating of a cylinder firing valve only if internal pressures have been adjusted by actuation of the safety valve by an operator. When safety valve is actuated, gas pressure drops in the valve housing, reducing pressure on the main valve side of cylinder firing valve, allowing movement of main valve and cylinder firing valve, while gas pressure flows into piston cylinder, moving downward the piston and driver blade assembly, and forcing ejection of a fastener from nailer. If safety trigger is not actuated, pressure remains constant around main valve and cylinder firing valve, remaining closed, and negating upward movement of cylinder firing valve with no movement of piston and driver blade assembly, despite striking of ram cap. Thus, the possibility of accidentally driving a fastener is virtually eliminated without operator's use of the safety trigger.

Abstract: The present invention provides a method for mass production of an antimicrobial peptide, which comprises the steps of: constructing a fusion gene containing a first gene encoding a negatively charged acidic peptide having at least two cysteine residues and a second gene encoding a positivel y charged basic antimicrobial peptide; transforming a host microorganism with an expression vector comprising the fusion gene; cultivating the transformed microorganism to express a fusion peptide containing the acidic peptide and the antimicrobial peptide; and, recovering the expressed antimicrobial peptide. In accordance with the present invention, the inhibitory effect of the expressed antimicrobial peptide on the growth of host microorganism can be dramatically minimized by fusing it with the acidic peptide. Accordingly, antimicrobial peptides can be produced massively from a recombinant microorganism regardless of the kind of the antimicrobial peptides.
