Abstract: ABSTRACT OF THE DISCLOSURE          The invention provides a small, inexpensive cleaning device that is particularly made to clean the grooves in the face of most golf clubs heads, both irons and drivers. The object of these grooves is to give the ball direction and backspin. If these grooves become clogged the player no longer gets the proper backspin on the golf ball and loses directional accuracy. The device has at one end a series of small evenly spaced fixed teeth, each reinforcing ribs to minimize the risk of the teeth breaking while the device is being used to clean the golf club head. The device can be twisted with respect to the golf club head to enable the cleaning of a variety of evenly spaced parallel grooves. Additionally, the device has a pair of large sharp prongs on its opposite end, which can be used to clean golf shoes and to repair divots and golf ball marks in the turf on golf course greens. The prongs have a bend that can be used in conjunction with the edge of a ball mark depression on the golf green as a fulcrum to leverage the turf back to a level shape. A thumb grip concavity is equipped with tread lines to prevent the user's hand from slipping onto the teeth when the prongs of the device are being used to repair turf.

Abstract: A method and apparatus for performing personal identification and/or verification at perdetermined stations or checkpoints is provided. Each person to be identified has a unit such as a card, badge or other token or device which stores a predetermined coded value, at least a predetermined portion of which is changed at selected time intervals in accordance with an algorithm, the algorithm being such that the value of the predetermined portion of the stored coded value at any given time is nonpredictable. The unit has a triggering signal generator, the unit being responsive to the triggering signal to present an indication of the current stored coded value to the station, the station responding to the predetermined coded value for identifying the person. Triggering may be in response to detection of a predetermined beacon from the station, in response to a user keypad input or may be periodically generated. Security may be enhanced by the person inputting a unique PIN at the unit which PIN is utilized in generating the nonpredictable codes. The PIN input may also be used for triggering. Verification may be achieved by including a public code as part of the code which is presented from the unit which public code is not changed.

Abstract: ABSTRACT OF THE DISCLOSURE       A universal, stand-alone controller integrated circuit (IC) for high resolution, active matrix liquid crystal displays (AMLCD's) incorporating the following features:  (1) serial to parallel conversion of the refresh data stream to support verti-cally split panels as well as multiple scan drives, (2) data re-ordering to support various color pixel/filter arrangements in-cluding delta-triad RGB and quad RGGB color filter mosaics, (3) two-dimensional anti-aliasing image processing, (4) color/gray-scale correction/compensation due to change in operating tempera-ture, and (5) host interface with programmable control registers to hold various display configurations and control parameters.          With these features, the stand-alone AMLCD controller simplifies the graphics/display adapter design by providing a simple single-panel single-drive interface, similar to that of the CRT's but in digital format, to various types of the AMLCD's.  It also reduces the functional and performance requirements of the AMLCD panel driver IC's by integrating pixel data rearrangement otherwise im-plemented in the driver IC's, hence allowing more line drivers to be integrated within a smaller driver chip.  The controller of the invention establishes a universal, standard interface between the host system and AMLCD's of various panel technologies, resolutions, and different timing requirements.
