  • Patent number: 7712742
    Abstract: In accordance with the principles of the present invention, a game of chance is provided. Cards for use in the game of chance have rows and columns that define “boxes having numbers contained in the boxes. A random number generator generates an initial number of numbers, preferably two. The initial numbers correspond to the numbers contained in the boxes, thus representing a numerical spread based on the position the numbers correspond to on the card. Depending on the numerical spread based on the position the numbers correspond to on the card, either a payoff is determined, a push is called or at least an addition number is generated. If the additional number is generated, either a payoff is determined or a push is called.

  • Patent number: 7716130
    Abstract: Methods and systems consistent with the present invention overcome the shortcomings of existing trading systems by providing an invoiceless trading system that creates incentives for customers to pay suppliers within a predetermined period of time, such as a settlement period. Specifically, the invoiceless trading system enables a customer to obtain a discount on orders placed with suppliers in return for an immediate payment (e.g., within 24 hours) by the customer. The supplier receives payment within the predetermined period of time, and the customer receives additional cash benefits by providing an early payment to the supplier. To communicate with and transfer funds between customers and suppliers, the invoiceless trading system may use an electronic gateway and a settlement bank. In addition to creating an incentive to embrace e-commerce, both customers and suppliers avoid the need to manually process orders and use invoices to complete transactions.

  • Patent number: 6217556
    Abstract: The present invention provides a drainage catheter for the therapeutic or diagnostic aspiration of fluid or air from the thoracic or abdominal cavities. The present invention provides a catheter needle, a catheter, a needle hub, a stop cock, and a self-sealing valve. The stop cock is removably secured to the catheter by use of a Luer connection. The stop cock is additionally removably secured to the self-sealing valve, again by use of a Luer connection. Use of the Luer connection allows the catheter to be disassembled from the stop cock as well as allows the stop cock to be disassembled from the self-sealing valve. This invention allows the additional medical procedures while the catheter still remains in the patient.

  • Patent number: 6103139
    Abstract: An activator (10) made in accordance with the principles of the present invention includes activating crystals (11) that have been formed into a shape and then coated with coating (12). The activator (10) of the present invention can be used in any environment in which the solidification of a supercooled solution occurs and whereby heat is generated during the solidification process. In the preferred embodiment disclosed herein, the activator is placed inside a hot pack (15) containing a supercooled solution (16). The hot pack can be made of a container made of a thermoplastic film which is formed into a bag, filled with activator (10) and the supercooled solution (16), and sealed to form the hot pack. The coating (12) of the activator (10) is impervious to the supercooled solution (16) in the hot pack (15) and into which the activator will be placed. The supercooled solution (16) may be any of a variety of chemical compositions known in the art which give off heat as they solidify.

  • Patent number: 6068612
    Abstract: The present invention provides an apparatus for detecting excessive air in a liquid flow-through tube. The apparatus includes an ultrasonic transmitter for transmitting ultrasonic signals and an ultrasonic receiver for receiving ultrasonic signals. The ultrasonic transmitter and ultrasonic receiver are separated by the IV tube. The apparatus further provides circuit means for generating at least two transmitting signals to actuate the ultrasonic transmitter and circuit means for detecting received signals. Means are provided for determining whether the received signal is indicative of air or liquid in the IV tube. The apparatus further relies on logarithmic detection of air in fluids rather than linear detection which provides a larger safety factor in prediction of air embolus.

  • Patent number: RE38776
    Abstract: A surgical instrument in the form of a biopsy needle for removing tissue samples from a patient. The device has means for preloading to excise tissue samples of a preselected one of many possible tissue sample sizes. After preloading, the procedure is easily accomplished using a single hand. The tip is rendered less traumatic by positioning the distal end of the tissue sample notch relatively close to the very distal tip of the stylet. This is accomplished by grinding the distal tip of the stylet into an elliptical shape in a plane having a lateral projection which is away from the distal end of the tissue sample notch.
