Abstract: An apparatus for embossing a fibrous web includes a mated pair of resilient and rigid embossing rolls 50,54 wherein the resilient roll 54 is formed e.g. by laser burning, with recesses 56 adapted to receive protuberances 52 on the rigid male embossing roll 50 when the rolls are placed in contact. By providing recesses on the resilient roll, the pressure or force required for causing the resilient material, e.g. rubber, to flow around the protuberances can be significantly decreased as compared to conventional rubber to steel embossing. As a result, wear on the rolls is reduced, and smaller diameter rolls may be utilized, thereby reducing the cost of the embossing equipment. In addition, since less pressure is required to cause the rubber to flow about the protuberances, roll deflection is not a problem, and an embossed pattern can be imparted having a consistent, high degree of definition across the width of a web.

Abstract: An optical recording system is described in which the optical head 31 is operated in physical contact with the surface of the optical recording medium during system operation at a selected operating speed. The optical head includes one or more optical elements 33 mounted on a substrate 37 which is in physical, sliding contact with the recording medium (30). The substrate is fabricated from a crystalline material which has a non-linear load versus friction characteristic in the negative load region. When the head is in sliding contact with the recording medium surface, a restoring force is generated which maintains the optical head in physical contact with the recording medium overcoming any lifting forces generated by the moving air layer adjacent the recording medium surface. This allows the head to be operated with a negative external load applied. Utilizing the optical head having the objective lens mounted on the substrate in close proximity to the recording medium surface allows high density recording to be achieved without the requirement of an electro-mechanical servo system to provide beam focusing for the system.

Abstract: A drive arrangement and operative scheme for the power switching transistors (111,112) of a half-bridge power converter drives the two power switching transistors with unequal duty cycles having conducting durations such that the sum of the conduction intervals substantially equals the combined switching period of the two power switching transistors. The conducting intervals are separated by very short dead time intervals controlled by the differing turn-on and turn-off times of the two power switching transistors. The short interval between alternate conductions of the two power switching transistors is sufficient to allow zero voltage turn on of the power switching transistors but short enough to minimize power loss and conducted noise. 
     Special biasing (120) is provided to prevent drive signal application to power switches prior to attainment of a minimum voltage across the switch. 
     Circuitry (130) is provided for cancellation of output ripple currents at selected operating points of the power converter.

Abstract: An object locating system, especially for use in locating a gaming ball in the game of football, utilizes a series of three sensors positioned on one side of a football playing field and a calibration source positioned on the other side. The calibration source emits an ultrasonic signal which is received by the sensors in order to provide a calibration signal. A ball marking unit is positionable on the field at a location of the ball and emits an ultrasonic signal which is received by the sensors and an RF signal which is received by the calibration source in order to turn the calibration source off. The sensors provide signals in which a processing unit calculates time delays by a time acquisition process in order to determine the position of the ball. In an alternate embodiment, the ball marking unit emits only an RF signal which is received by the sensors. The sensors again provide signals which are analyzed by the processing unit to determine delay between receipt of the signals at the sensors. Additionally, an automatic ball marking unit on a track drive can be controlled by the processing unit to automatically provide a visual representation of the ball's location.

Abstract: A method and an apparatus allows multiple users to share one or more data communication lines without requiring the users to actively participate in the arbitration. The preferred embodiment comprises an ISDN Port Connection Manager (PCM) for managing the use of each of the individual channels of one or more line ports having ISDN service thereon. The ISDN PCM manages the use of the channels between applications using such distinct access methods as IBM's Virtual Telecommunications Access Method (VTAM), TCP/IP, and Open Systems Interconnect (OSI) access methods. The ISDN PCM determines that an application needs access to an ISDN channel, determines the availability of the ISDN network and sets up the communication between the application and the network if the channel is available. If no channel is available at that time, the ISDN PCM indicates to the application when the channel becomes available so that the application may determine whether it still needs access.
