Abstract: The present invention is directed to a system, method and article of manufacture for testing and design verification of hardware devices by providing for random accesses to the registers of a device under test. Such random accesses may more closely resemble actual accesses to the registers of a device during normal operation, thus providing a more thorough test.

Abstract: Methods for securing data by using a data encoding technique of a symbology, such as a one or two-dimensional symbology, to provide secure data without the need to convert the data into a graphical symbol are provided.

Abstract: A cellular phone call management system using a microprocessor-controlled remote card reader interface for a cellular telephone system to record calls onto a card as they are placed or received. A microprocessor reads information from a card placed in the remote card reader and ensures the card is valid. The cellular telephone's transceiver logic bus is monitored to determine the transaction information of a call as it is placed or received. After the call is completed, the call transaction information is recorded on the card. When all calls are complete, the card is placed in a host card reader attached to a host computer where the call transaction information is read from the card, processed, and written to a host storage device. The call transactions may then be analyzed and reports may be generated and printed by host computer software.

Abstract: A secure computer controlling access to data storage devices via a card reader. A microprocessor-controlled card reader interface logically connected to the card reader and the central processing unit (CPU) of the computer reads and writes information from and to a card placed in the card reader and performs additional functions in response to commands received from the CPU. The card reader interface includes an encryption engine for encrypting data in a data storage device and a boot ROM containing verification program code executed during an initialization procedure. The verification program verifies that a valid user card has been placed in the card reader, reads one or more questions from the user card, asks the questions of the user and verifies the answers against the contents of the card. If authorization is verified, the card reader interface permits the user to access the encrypted data.

Abstract: An ophthalmic examination chair having an integrated positioning capability for providing wheel chair access to an associated instrument stand accommodating the examining of disabled patients. The chair has a seat member which is configured to receive a seated patient and is movable from a forward position spacing the seated patient at a predetermined distance from an eye examination target. A lower base member is provided as extending along a longitudinal axis between a forward end and a rearward end, and as having an upper and a lower surface. An upper carriage member, having a bottom surface and a top surface supporting the seat member thereon, is supported on the upper surface of the base member for movement between the forward and the rearward end thereof along the longitudinal axis to position the seat member at the forward position and at a rearward position providing access to the instrument stand by a wheel chair patient positioned at the predetermined distance from the eye examination target.

Abstract: A positioning system for moving an ophthalmic examination chair used in conjunction with an associated instrument stand between a forward position spaced a predetermined distance from an eye examination target and a rearward position providing access to the instrument stand by a patient in a wheel chair. A lower base is provided as extending along a longitudinal axis between a forward end and a rearward end, and as having an upper and a lower surface and a widthwise extent configured as being receivable between the wheels of the wheel chair. An upper carriage, having a bottom surface and a top surface configured to receive the examination chair thereon, is supported on the upper surface of the base for movement between the forward and the rearward end thereof along the longitudinal axis to position the examination chair at the forward and the rearward position.

Abstract: A secure computer controlling access to internal devices via an integrated card reader. A microprocessor-controlled card reader interface logically connected to the CPU of the computer reads and writes information from and to a card placed in the card reader and performs additional functions in response to commands received from the CPU. The boot ROM of the computer is programmed to start execution from a program logic device which runs a verification program to verify the authenticity of a user. Upon a valid user card being placed in the card reader, one or more questions are read from the card and displayed to the user. The user's responses are saved and compared to the correct answers stored on the card, and if the responses match the correct answers, a power control circuit is used by the CPU to turn on power to computer peripherals the user has been authorized to use.The system additionally provides for a method of initializing and authorizing a user card with a security administrator card.

Abstract: An illuminator assembly is provided for ophthalmic refractors which is formed as a singular light guide formed in unitary fashion of a transparent polymeric material. The light guide includes a light input portion located adjacent an incandescent light source mounted within the refractor housing. The light guide has transparent output portions which extend uniformly and continuously about the axis scale and further extend to the cylinder power window and the spherical power window. Through the use of a potentiometer/voltage regulator based circuit, the practitioner may alter the intensity of the light propagated to these readout functions by maneuvering a knob mounted upon the battery housing. To improve the characteristics of the illumination, the transparent outputs of the light guide are formed as Fresnel lenses.

Abstract: A syringe disposal apparatus has a portable collection unit (1) and a processing unit (2'). The collection unit (1) has an in-feed mechanism (11) to allow syringes to be introduced into the collection unit (1); and an interlock mechanism (12) suitable for removably securing the collection unit (1) to the processing unit (2') and emptying the syringes from the collection unit (1) into the processing unit (2').

Abstract: A syringe disposal apparatus has a portable collection unit and a process unit. The collection unit has an in-feed mechanism to allow syringes to be introduced into the collection unit; and an interlock mechanism suitable for removably securing the collection unit to the processing unit and emptying the syringes from the collection unit into the processing unit. The processing unit contains an interlock mechanism suitable to activating the collection unit interlock mechanism; a grinder suitable for grinding the syringes into particles of metal and plastic; and a crucible assembly suitable for heating these particles above the melting point of plastic, and then cooling to produce a solid puck of plastic in which the metal particles are suspended and encapsulated.

Abstract: Methods and kits are set out having improved selectivity and improved sensitivity for use in field and home immunoassays. A specifically binding biomaterial is attached to a macroextensive surface of a plastic strip or the like. A biological substance which is a specific binding partner to a binding site of the specifically binding biomaterial is attached to each of a plurality of synthetic particles. The particles are of a preselected size, refractive index, or the like to enhance their visibility in accordance with the Mie scattering phenomenon. Testing is by either contacting the particles with the strips to obtain adherence of the particles to the strips, or by exposing strips having the particles already adhering to them to a solution containing either the specifically binding biomaterial or the biological substance, whereby the particles adherence to the strip is eliminated. A quick and accurate pregnancy test is one result of the invention.
