Abstract:
A shelf assembly is provided with a spring-assisted shelf for an oven appliance. A spring is placed into tension as the oven door is closed and the oven shelf is slid towards the rear of the oven cavity. As the door is opened, the spring retracts so as to cause the oven shelf to slide forward at least partially out of the oven cavity. The shelf assembly is vertically adjustable and can be removed from the oven cavity for repositioning at another height therein.
Abstract:
A vehicle control system determines an upper non-zero limit on deceleration of a vehicle to prevent rollback of the vehicle down a grade being traveled up on by the vehicle. The upper non-zero limit on deceleration is determined by the controller based on a payload carried by the vehicle, a speed of the vehicle, and a grade of a route being traveled upon by the vehicle. The controller is configured to monitor the deceleration of the vehicle, and to automatically prevent the deceleration of the vehicle from exceeding the upper non-zero limit by controlling one or more of a brake or a motor of the vehicle. The controller also is configured to one or more of actuate the brake or supply current to the motor of the vehicle to prevent rollback of the vehicle while the vehicle is moving up the grade at a non-zero speed.
Abstract:
A resonator device 10 is disclosed. The resonator device may be used in a transducer or a sensor such as a pressure, force or acceleration sensor. The resonator device comprises a resonator 20 provided on a diaphragm 30. A cap 40 is provided which may be fusion bonded to the diaphragm 30 to enclose the resonator 20 and form a hermetically sealed package 10. The resonator device is excited by applying electromagnetic stimulation, such as infra-red or optical stimulation, which may be from a laser via a fibre 50. The resonator device may be interrogated by applying an electromagnetic signal into the optical cavity formed between the resonator 20 and the inside surface of the cap 40 to derive a frequency change of the resonator. As the resonator device incorporates a hermetically sealed package and is stimulated by electromagnetic radiation, it is robust and able to operate in harsh environments.
Abstract:
Scintillator materials based on certain types of halide-lanthanide matrix materials are described. In one embodiment, the matrix material contains a mixture of lanthanide halides, i.e., a solid solution of at least two of the halides, such as lanthanum chloride and lanthanum bromide. In another embodiment, the matrix material is based on lanthanum iodide alone, which must be substantially free of lanthanum oxyiodide. The scintillator materials, which can be in monocrystalline or polycrystalline form, also include an activator for the matrix material, e.g., cerium. To further improve the stopping power and the scintillating efficiency of these halide scintillators, the addition of bismuth is disclosed. Radiation detectors that use the scintillators are also described, as are related methods for detecting high-energy radiation.
Abstract:
A method for determining analyte concentration levels is provided. The method includes acquiring radiation scattered off or transmitted by a target, analyzing at least a first portion of the radiation via a first technique to generate a first measurement of analyte concentration levels, and analyzing at least a second portion of the radiation via a second technique to generate a second measurement of analyte concentration levels. The method further determines analyte concentration levels based on at least one of the first measurement or the second measurement. In addition, a system for implementing the method and a probe for measuring and monitoring the analyte concentration levels is provided.
Abstract:
An organic photovoltaic ('PV') device comprises a plurality of organic PV cells connected in series to cover a large area. The organic PV device optionally has an electrical circuit element connected in parallel to each organic PV cell. The organic PV device allows for continued operation even when short circuits develop or electrical interruption occurs in one of the cells. The device is conveniently manufactured using a shadow mask, which allows for the formation of several consecutive layers in one apparatus.
Abstract:
Cyclic siloxanes that contain releasable active ingredients are described. The active ingredient can be an alcohol or enolizable carbonyl-containing compound such as a ketone, aldehyde, or ester. The product siloxanes are useful in a variety of personal and household care products where slow or controlled release of active ingredient is desired. A preferred embodiment utilizes substituents that when released as active ingredients are fragrant.
Abstract:
A method and Apparatus for measuring water of hydration in a polyelectrolyte membrane (PEM) employs a source of input radiation directed at an input location on the PEM; and a detector responsively positioned at an output location relative to the input location for determining a sensible change in the input radiation indicative of a level of water hydration in the PEM. The method measurs hydration of the (PEM) by forming an input location in the PEM; launching a source of radiation (34) into the input location for reaction with the PEM material; detecting the reaction (40) of the input radiation with the PEM material; and determining a sensible change in the input radiation as a result of the reaction indicative of a level of water hydration in the PEM (50).
Abstract:
The process for stator bar rewinds includes disassembly of the stator bars at the generator site, measurement of the stator bars, forwarding digital representations of the measurements to a manufacturing center and forming 3-Dimensional models of the stator bars requiring replacement and the stator. The stator bar 3D model is placed in the stator 3D model to insure accuracy of fit. Tooling and stator bar drawings are generated and sample stator bars are manufactured. 3D modeling of the manufactured sample stator bars are compared to the nominal 3D models to insure accuracy. The replacement stator bars are manufactured and forwarded in batches for assembly into the extant generator.
