  • Patent number: 5563576
    Abstract: A vehicle security siren that includes a rechargeable back-up battery and an electronic circuit that minimizes current drain from the vehicle's battery by controlling the rate at which the siren's back-up battery is charged by the vehicle's battery. The circuit charges the siren's battery at a relatively high rate when the vehicle engine is running or the ignition is on, and by a low charging rate at other times. This multi-level charging rate preserves the vehicle's battery charge particularly if the vehicle is not driven for any extended time period. The circuit includes a back-up battery condition detector that issues a warning signal in the event of failure of the back-up battery. The circuit also limits the maximum siren duration in the event that either the vehicle's battery or the security system is disconnected from the siren.

  • Patent number: 5529441
    Abstract: A system and method for optimizing drill coordinates in a multi-layer printed circuit board, to correct for interlayer shift during lamination. A set of test patterns, in the form of a cross formed by two orthogonal conductor lines, are defined at each corner of each layer in the same nominal location. Under ideal conditions, the test patterns of the layers in each corner are lined up one above the other, without any offset. A counter sinking tool is used to cut a conical bore in the location of the test patterns, so that every test pattern cross is interrupted in four places, generating a four segment pattern in each layer. A high resolution camera is placed above the countersunk bore to form a single image of the exposed segment edges of all the test patterns exposed by the bore. The image is analyzed to determine the amount of shift of each layer. If all patterns are perfectly concentric, all crosses are perfectly aligned.

  • Patent number: 5518240
    Abstract: A method of fabricating a metal wood club head. The head is fabricated in two half-sections, each formed by a casting technique. The two half-sections are subsequently joined by welding together facing edges of the respective half-sections along a parting line. The parting line extends through the highest point in the head crown, generally parallel to the face region and behind the hose. The placement of the parting line permits the use of simple one-piece mold cores, since there are no negative angles within the half-section elements to prevent such a core from being removed. The method is low cost, and provides a high strength club head, with the weld joint located away from club stress points.

  • Patent number: 5467070
    Abstract: A vehicle security system having a secure valet/programming switch. To either enter the system valet mode, or select a function via the valet/programming switch, the user must first enter a valid personal access code via the switch. To prevent an intruder from deciphering the personal code by trying various codes, the system ignores, after a preset number of successive invalid entries, further switch inputs for a preset period of time. When attempts to decipher the code are detected, the alarm is tripped, and the siren will sound. To accommodate various drivers of the same vehicle, more than one valid code can be stored in the system. Any of the personal access codes may be changed any time, but after the user's present code is entered.

  • Patent number: 5437088
    Abstract: An improved golf club wherein the surface of the face of the club is substantially flat, which is achieved by surfacing (milling) the club face, and wherein the edges of scoring lines (grooves) are made relatively sharp as a result of the surfacing operation. The sharp groove edges (and milling lines) of the present invention produce enhanced backspin and reduced sidespin when a golf ball is struck, which results in a relatively straight golf ball flight path, notwithstanding a glancing club impact angle. In addition, milling lines that may be formed on the club face are generally parallel to the scoring lines and hence enhance the club characteristics. The present invention also provides for methods of making a golf club that has the above features, including forging and casting methods. In either method, a club is processed to produce generally smooth and finished features with scoring lines formed in the face of the club.

  • Patent number: 5398746
    Abstract: A metal wood golf club head with a hollow body shell of a first lightweight material and a sole plate of a second material having a higher specific weight density than the first material. The sole plate is attached to the shell without welding, fasteners or force-fitting. The center of gravity of the head is lowered, and other weight distributions can be achieved by alternate sole plate configurations, such as heel, toe or rear weighting. The head is fabricated by a process which includes the steps of providing the sole plate of the second material, disposing a core adjacent the interior surface of the sole plate, disposing an exterior mold about the core so that the exterior mold, the core and sole plate collectively define a mold cavity in the form of the body shell, filling the cavity with the second material in a fluid state, and permitting the second material to solidify. Upon solidification, the second material locks onto the sole plate, fixing the sole plate in position.

  • Patent number: 5218487
    Abstract: A computer storage DAT drive which detects the form of a DAT tape and provides an audio signal output in response to an audio DAT tape. The drive rewinds the tape and then plays the tape at a speed that is about 5 to 15 times normal playback speed. During such playback, the tape length is determined and the subcode information is read to determine the format of the tape being played back. If the subcode tape format information reliably indicates the presence of an audio tape, the speed of playback is reduced to normal playback, and audio data interface circuitry is enabled for processing the audio data and providing an audio output signal to a front panel audio jack, for example. If the tape is not recognized as an audio tape within the playback of a predetermined length of tape, playback speed is reduced to normal playback speed and reading of the subcode information continues.
