Abstract: A parking guidance system for large vehicles has a horizontal bar, a data collection assembly and a console unit. The horizontal bar is hollow and is mounted on the rear bumper, and houses the data collection assembly. The data collection assembly uses multiple ultrasonic transmitter and detector modules and an option vide camera module. A console unit mounted in a driver compartment receives data from the data collection assembly and processes the data to proved warnings to a user.

Abstract: A criminal arresting method includes preparing a frame assembly, activating a first weight releasing device to allow a first weight to fall inside the frame assembly, activating reducing of size of a first loop inside the frame assembly, activating a second weight releasing device to allow a second weight to fall relative to the frame assembly and activating reducing of size a second loop inside the frame assembly.

Abstract: A combustion air system for a recovery boiler is described in which multiple levels of secondary and tertiary combustion air ports each have an even number of ports, with the ports on opposing walls interlaced. The air system lends itself equally well to front/rear wall or sidewall applications and is especially beneficial for rectangular boilers. The air system features large and small-scale horizontal circulation zones superimposed on each other and the ability to adjust the angle of the air jets. Additional features include port dampers for the starting burners and system control based on kinetic energy.

Abstract: A digital indoor antenna device having a casing, a pivotal seat, a circular antenna having two ends and a PCB in the casing. The pivotal seat attached to the casing has two mounting holes respectively in which the two ends of circular antenna are mounted. The circular antenna rotates on the casing to adjust the horizontal receiving angle. Therefore, the circular antenna device can receive larger intensity of horizontal polarized signals. In addition, the pivotal seat can be pivotally connected to the casing, so the circular antenna can rotate horizontally on the casing to search for different channel signals.

Abstract: The present invention is directed to a speaker using lightweight, highly rigid diaphragm having excellent frequency characteristic and improving resistance to environment (including resistance to UV and resistance to fading). For this end, the speaker utilizes a cone-shaped diaphragm made from foamed or cellular resin such as polyethylene terephthalate (PET) resin or polyethylene naphthalate (PEN) resin with 30 ?m average cell size. The use of such cone-shaped diaphragm is effective to improve sound quality of the speaker.

Abstract: A golf club head includes a head body having a recessed area defined in a central area of the head body and abutting faces formed along a periphery defining the recessed area. A soldering seam is formed on an outer periphery defining the recessed area and at least one positioning block is formed on one of the abutting faces and has a bottom face flush with a top face of the recessed area. A striking face is abutted to the abutting faces and the bottom face of the positioning block to allow the soldering seam to securely combine the head body and the striking face.

Abstract: A system and method for locating a data sample in a logic analyzer or emulator acquisition buffer corresponding to a source code statement employs first and second windows, wherein one window displays the contents of the acquisition buffer, for example, in disassembly form and the other window displays source code. When a source code file is displayed and a specified statement is selected within the source code, a search for a matching sample in the acquisition buffer is initiated. If a sample is found, it is displayed and highlighted in the appropriate window.

Abstract: An improved open circuit detector for testing a thermocouple for an open circuit condition. The detector includes a generator for providing and sourcing a tone signal to the thermocouple, wherein the tone signal has a known frequency and amplitude. A monitor analyzes the amplitude of a particular frequency component of a tone signal across the thermocouple. If the amplitude of the particular frequency component exceeds a predetermined threshold, an output is provided for indicating an open circuit condition for the thermocouple.

Abstract: An apparatus for providing an electrical connection between an electrical connector and a conductive chassis member includes aligned connector holes in the chassis, a thin ground sheet of springy and conductive material and a thicker support plate. The holes in the thin ground sheet have a periphery that includes alternating gaps and extensions, with the dimension defined by the gaps being larger than the corresponding dimension of the barrel of the electrical connector and the dimension defined by the extensions being smaller than the dimension of the barrel. The thin ground sheet is held in physical and electrical contact with and parallel to the conductive chassis member by the support plate, which is also preferably of conducting material, and a set of screws.
