  • Patent number: 10327834
    Abstract: A method for manufacturing an end effector assembly includes providing first and second jaw members moveable relative to one another about a pivot between a first, spaced-apart position and a second, approximated position. One of the first and second jaw members includes a cavity defined therein and the other of the first and second jaw members includes a stop member configured to be inserted into the cavity. A gap-setting gauge is grasped between the first and second jaw members to define a gap-distance between the jaw members equivalent to a thickness of the gap-setting gauge. The first and second jaw members are set such that the jaw members are prevented from approximation beyond the gap-distance.

  • Patent number: 9273831
    Abstract: An improved LED light source assembly is described, suitable for use as a retrofit for prior lighting fixtures of a kind including a concave reflector, an incandescent lamp positioned with its filament(s) at or near a focal region of the reflector, and a lens assembly for projecting light reflected by the reflector to a distant location, e.g., a theater stage. The improved LED light source assembly includes a compact arrangement of three or more LED assemblies, which are mounted at the forward end of an elongated heat pipe. The heat pipe's rearward end attaches to a heat sink mountable on the back side of the lighting fixture's concave reflector, and the heat pipe extends through a central hole in the reflector to position the LED assemblies at or near the concave reflector's focal region. The concave reflector reflects light emitted by the LED assemblies forward to the lighting fixture's lens assembly, which in turn projects a beam of light to a distant location.

  • Publication number: 20140081668
    Abstract: A method of delivering goods or services via an encoded medium to a holder includes generating data in a database associated with a central computing station in response to an assignee of the medium and a provider of goods or services separately communicatively linking the medium to a central computing station. The data generated in the database includes the identity of the assignee, the identity of the goods or services associated with the medium, and the identity of the goods or services provided by the provider. A value of the medium is established, wherein the medium assumes different values based on various conditions. After the provider of goods or services provides the goods or services to the holder, the value of the medium is updated and recorded in the database.

  • Publication number: 20130304483
    Abstract: A method implemented by a trusted third-party computing system assists a manufacturer of a prescription pharmaceutical product to promote that product by authorizing a pharmacy that makes one or more sales of the product to make one or more future purchases on promotional payment terms. The method includes receiving one or more electronic notifications that indicate the pharmacy has made one or more sales of the prescription pharmaceutical product to one or more patients, and then validating that the one or more indicated sales have actually occurred. Validation may entail validating data fields in each received notification and/or validating that the one or more sales are consistent with the pharmacy's inventory. Responsive to this validation, the method includes generating and sending control signalling based on the one or more indicated sales for triggering the manufacturer to authorize the pharmacy to make one or more future purchases on promotional payment terms.

  • Publication number: 20130246087
    Abstract: A method for distributing a prescription pharmaceutical product includes recording a unique identifier in a database that identifies a medium and a prescription pharmaceutical product associated with the medium. The database is provisioned with criteria that establish different potential values for the medium. Thus, the medium has a variable value that varies according to the criteria provisioned in the database. A holder of the medium then presents the medium to a provider of the prescription pharmaceutical product. Upon receipt the medium, the provider communicates the unique identifier associated with the medium. Based on the unique identifier of the medium and the variable value criteria provisioned in the database, the value of the medium is determined and communicated to the provider. The holder then utilizes the determined value to purchase the prescription pharmaceutical product associated with the medium.

  • Patent number: 8407095
    Abstract: One or more embodiments include a method of delivering a pharmaceutical product via a medium. The pharmaceutical product is associated with the medium and the medium assumes different values based on predetermined business rules. The method includes generating data in a database associated with a central computing station where the data identifies the medium and the product associated with the medium. The database is provisioned with the rules that determine the value of the medium. In response to the holder presenting the medium to a provider of the product for purposes of obtaining the product, a communication from the provider is received identifying the medium. A value for the medium is established based on the rules provisioned in the database. The value of the medium is updated, and that updated value is recorded in the database in response to the provider providing the product to the holder of the medium.

  • Publication number: 20130041675
    Abstract: A method of distributing and tracking donated prescription medicines includes a pharmaceutical donor donating in-kind pharmaceutical products to a non-profit organization which then transfers the donated pharmaceutical products to a pharmaceutical distributor. An electronic record is established indicating a credit with pharmaceutical distributor in favor of the non-profit organization. After a pharmacy has distributed a pharmaceutical to an eligible patient, the pharmacy notifies the non-profit organization of the transaction and the non-profit organization authorizes the pharmaceutical distributor to apply to the credit to the benefit of the pharmacy.

  • Patent number: 8267547
    Abstract: An improved incandescent lamp and incandescent lighting system are disclosed, for projecting a beam of light with substantially improved energy efficiency. The incandescent lamp includes a pair of reflective ceramic filament supports for supporting one or more filaments in prescribed position(s) within an envelope while reflecting back substantially all visible and infrared light for incorporation into the projected beam or for absorption by the filament(s). The incandescent lighting system includes a special infrared-reflective shroud concentrically encircling the incandescent lamp, for reflecting infrared light back toward the lamp filament(s) while transmitting visible light to a concave reflector for incorporation into the projected beam. The infrared-reflective coating is deposited onto the shroud's inner surface, and it includes a dielectric coating and an underlying transparent conductive coating.
