摘要:
A method for separating biological cells characterized by the steps of suspending a mixed cell population in a body of aqueous polymer comprising a system consisting of phases for which said cells exhibit an affinity including at least one phase having droplets characterized by a first surface potential and at least one phase having droplets characterized by another surface potential, and subjecting said system to an electrostatic field established between a pair of electrodes, said field being of sufficient intensity for causing at least some of the droplets to migrate toward one of said electrodes with an attendant separation of the cells of said population.

An ink jet printer has two print cartridges. For example, one cartridge can carry black ink and the other red ink. Both cartridges are used to print on a receipt with a narrow print zone of, for example, 2.5 inches. Only the black cartridge is used to print on a cut sheet for validation purposes. By lengthening the time that the print head of the black cartridge is actuated to spray ink, a wider print zone (e.g., 3.5 inches) can be provided for the cut sheet.

A configurable printer for different locations and methods for configuring a printer for different locations are provided. The printer includes memory loaded with different versions of firmware. Each version of firmware may enable a different printer configuration for a corresponding location. The printer also includes an interface for accepting a signal from a control device. The signal may comprise instructions to the printer to load a particular version of the firmware that corresponds to the location of the control device.

Methods are disclosed for driving a printer to print highly secure vouchers and less secure coupons. The printer can reside, for example, in a wagering terminal (e.g., slot machine), ticket machine, point-of-sale terminal or the like. A first driver receives, e.g., from a primary controller, data indicative of voucher information to be printed. A second driver receives, e.g., from a secondary controller, data indicative of coupon information to be printed. A processor responsive to the first and second drivers generates printer commands in a standard printer format so that the same printer can be used to print vouchers and coupons. Coupons do not have to be processed by the secure (and usually proprietary) hardware and/or software provided by the terminal manufacturer for printing vouchers.

Embodiments presented herein relate to various polymers. Some of the polymer embodiments are heparin binding polymers. Some embodiments of the heparin binding polymers can be employed to bind to heparin for methods such as separating, purifying, removing, and/or isolating heparin and heparin like molecules.

Methods and apparatus for converting a firmware download port on a printer to a communications port are provided. The apparatus includes a printed circuit board arrangement connected to the firmware download port of the printer. A secondary communications port is provided on the printed circuit board arrangement for enabling communications between the printer and a central system controller. The printer may include one or more primary communications ports. Each of the one or more primary communications ports may be selectable for enabling communications between the printer and a local controller. The local controller may provide data to the printer via a selected one of the primary communications ports indicative of cash information to be printed on a voucher. The central system controller may provide data to the printer via the secondary communications port indicative of non-cash data to be printed on a coupon.
摘要:
A method of improving heart function in a subject, the method comprising administering an effective amount of a hyperbranched polyglycerol to a subject. The improvement in heart function may include one or more of an increase in myocardial contractile function, reduced or absent fibrosis, an increase in mechanical efficiency of the heart, an increase in ejection fraction, an increase in glucose oxidation or a decrease in fatty acid oxidation, as determined by conventional methods known in the art.
摘要:
An electrical device is disposed on a base for sliding movement between first and second ends of the base. The electrical device includes a first electrical connector configured to connect to a connector board disposed on the base. The connector board includes a second electrical connector configured to mate with the first electrical connector. The connector board can move between the first and second ends. A cable electrically couples the second connector to a signal. The cable is configured to maintain electrical connectivity between the signal and the second connector as the connector board slides between the first and second ends. The electrical device can removably connect to the connector board via the first and second connectors. The connector board can slide along with the electrical device to provide electrical connectivity of the signal to the electrical device as the electrical device slides between the first and second ends.
