  • Publication number: 20040238358
    Abstract: A biosensor for determining the concentration of an analyte in a biological sample. The biosensor comprises a support, a reference electrode or a counter electrode or both a reference and a counter electrode disposed on the support, a working electrode disposed on the support, the working electrode spaced apart from the other electrode or electrodes on the support, a covering layer defining a sample chamber over the electrodes, an aperture in the covering layer for receiving a sample, and at least one layer of mesh in the sample chamber between the covering layer and the electrodes. The at least one layer of mesh has coated thereon a silicone surfactant. Certain silicone surfactants are as effective as fluorinated surfactants with respect to performance of biosensors. These surfactants, when coated onto the mesh layer of the biosensor, are effective in facilitating the transport of aqueous test samples, such as blood, in the sample chamber.

  • Patent number: 6734974
    Abstract: A method of improving spatial resolution of a pump-probe terahertz (THz) imaging system for producing an image of an object. The method provides a chopped optical gating beam focused on a semiconductive layer that is either part of the object or a discrete layer placed over the object. The gating beam is focused on a gating pulse focal spot having a diameter effective to cause measurable modulation in transmission of a THz beam through the semiconductive layer when the gating pulse is on as compared to when the gating pulse is off, creating alternating modulated THz beams for detection and processing. Systems for performing the method in transmission and reflection modes are also described.

  • Publication number: 20040057456
    Abstract: In a communication system, a subscriber unit includes a storage device storing an application program to determine for transmission a current reserved bandwidth and a transmission parameter based on a quality of based on a quality of service profile, and an adapter to communicate data over a wireless network (e.g., a general packet radio service network) that supports a service, satisfying a reliability requirement for the service. The adapter may dynamically adjust the transmission parameter for the transmission before retransmitting one or more packets of data, e.g., at a rate and retransmission times commensurate with the current reserved bandwidth, and the reliability requirement in addition to the a current quality of service profile, ensuring a service level which otherwise cannot be provided by an infrastructure negotiated quality of service, especially in relatively shorter flows of data.

  • Patent number: 6690001
    Abstract: A method and apparatus for measuring electromagnetic pulses as a function of time. Radiation measurement, including measurement of single-shot, free-space terahertz femtosecond pulses, is realized using an electro-optical modulator in combination with an optical streak camera. This method and apparatus allow measurement of electromagnetic pulses previously unmeasurable due to the time resolution restrictions dictated by the time-frequency correlation.
