摘要:
A programmable logic device (PLD) includes a non-volatile memory, a configuration memory, and a control circuitry. The control circuitry couples to the non-volatile memory and to the configuration memory. A set of voltages are derived from the outputs of the control circuitry, and are applied to circuitry within the PLD.

An apparatus, program product and method for determining unreturned standby resource usage. Unreturned standby resource data is monitored and stored separately from other standby resource data for billing and other accounting purposes.

A method for calibrating a radiation detection medium by exposing arbitrary locations of a radiation detection medium to a plurality of known radiation dose levels is described. One particular aspect of the method includes the steps of automatically determining the location of each arbitrary exposed location, measuring the density of each of the arbitrary exposed locations, matching each measurement for the arbitrary exposed locations with the corresponding radiation dose level thereby generating an array of paired data values for radiation dose level and measured density and calculating a calibration based on the array of paired data values.

A metal implant for use in a surgical procedure is provided with a surface layer that is integral with the metal substrate, and which incorporates a biocidal material. The surface layer is grown by anodising at a voltage between 50 and 150 V, and the biocidal material incorporated in it by ion exchange. This produces a significantly harder surface than anodising at low voltage, and generates pits containing ion-absorbing material.

A programmable logic device (PLD) includes a delay circuit and a body-bias generator. The delay circuit has a delay configured to represent a delay of user circuit implement in the PLD. The body-bias generator is configured to adjust the body bias of a transistor within the user circuit. The body-bias generator adjusts the body bias of the transistor in response to a level derived from the signal propagation delay of the delay circuit.

A method and apparatus of defining a time interval includes providing a source of ionizing radiation that radiates emissions thereof; placing a radiation sensitive display material responsive to ionizing radiation in a close proximity relationship to the source of ionizing radiation whereby the radiated emissions of the source strike the radiation sensitive display material, thereby commencing a time interval; and, measuring changes in characteristics of the radiation sensitive display material that are indicative of the elapsed time.
摘要:
Endogenous gene regulation mechanisms together with microRNAs expressed in many organisms can be used to provide regulated or conditional expression of transgenes by placing an appropriate sequence, a microRNA binding site, within the transcribed gene. This microRNA-dependent transcription regulation can be further regulated using microRNA inhibitors.
摘要:
A programmable logic device (PLD) includes first and second circuits. The first and second circuits are part of a user's design to be implemented using the PLD's resources. The first circuit is powered by a first supply voltage. The second circuit is powered by a second supply voltage. At least one of the first and second supply voltages is determined by a PLD computer-aided design (CAD) flow used to implement the user's design in the PLD.
摘要:
An article of manufacture comprising a radiation sensitive material, and a measuring scale that is part of the radiation sensitive material. A method of measuring at least one parameter relating to an irradiated material is also described. A radiation sensitive material including a measuring scale is exposed to radiation and at least one parameter relating to one or more exposed areas of the material is measured by reference to the measuring scale on the material.
