Abstract: An optical system comprising two lens cells, each lens cell comprising multiple lens elements, to provide imaging over a very wide image distance and within a wide range of magnification by changing the distance between the two lens cells. An embodiment also provides scannable laser spectroscopic measurements within the field-of-view of the instrument.

Abstract: A circuit that may be configured to store data and interface with an external device. The circuit may provide one or more control signals to the external device.

Abstract: Provided are methods for conferring resistance to porphyrin-accumulating type herbicides upon plant or algal cells using DNA fragments or biologically functional equivalents thereof isolated from Chlamydomonas reinhardtii, and herbicide-resistant plants or algae into which these DNA fragments or biologically functional equivalents thereof have been introduced and in which they are expressed.

Abstract: A device and method for interconnecting two universal serial buses (USBs) is provided in which the device controls the current supplied to the device from the USBs via a power manager. In particular, when one or both of the buses connected to the device enter a suspended state, the power manager reduces the current consumed by the device so that the device does not exceed a maximum suspend current. The device may also have a power manager controller which permits one or both device drivers connected to the USBs to control the power manager.

Abstract: A method of treating an article with a mixture of ethylene oxide gas, air, and an inert gas which makes possible reuse of the ethylene oxide for an indefinite number of successive treatment cycles. The gas mixture is refortified with ethylene oxide when necessary. Nonflammability is maintained by removing air from the treatment tank before the mixture is admitted into the tank by the evacuation of the tank to a predetermined pressure, the admitting of an inert gas to the tank to a predetermined pressure, and the subsequent removal of the resulting air and inert gas mixture from the tank by evacuation to a predetermined pressure, the air removal resulting in an air proportion less than or equal to that proportion residing in the treatment mixture that is maintained in the holding tank.
