20130083822 | IR SENSOR FOR ELECTRONIC THERMOMETER - An electronic thermometer includes a probe adapted to be heated by a subject for use in measuring a temperature of the subject. At least one temperature sensor detects a temperature of the probe. An IR emitter emits an infrared signal from the probe. And an IR detector detects the infrared signal emitted by the IR emitter. The detection of the IR signal by the IR detector indicates that the probe is received in a probe cover. | 04-04-2013 |
20130294941 | OPTICAL DETECTION OF MEDICAL PUMP ROTOR POSITION - Rotation of a rotatable assembly of a medical pumping apparatus such as a pump rotor of a rotary peristaltic pump is monitored via electromagnetic radiation (e.g., infrared radiation). The rotatable assembly is formed such that it has portions that are reflective and non-reflective with respect to the electromagnetic radiation. A electromagnetic radiation emitter-detector pair is positioned such that as the rotatable assembly rotates, the reflective and non-reflective portions alternately pass through the electromagnetic radiation emitted by the emitter. The detector receives electromagnetic radiation reflected by the reflective portions, but the non-reflective portions absorb or disperse the radiation such that it is not received by the detector. An output circuit provides a signal indicating the position of the rotatable assembly as a function of the electromagnetic radiation received by the detector. | 11-07-2013 |

20140296775 | FLUID DETECTION IN AN ENTERAL FEEDING SET - Detection of fluid conditions in an administration set. A light source is positioned to transmit an infrared light through administration set tubing and any fluid therein. A light sensor senses the infrared light transmitted through the tubing and generates an output signal. A frequency of the output signal is a function of an intensity of the light transmitted through the tubing. A processor receives and determines the frequency of the output signal, and compares the determined frequency to threshold frequency values to determine whether fluid is in the tubing. The processor also monitors the generated output signal to determine if the frequency of the output signal changes over time, and determines whether fluid is flowing in the tubing as a function of the determined change in frequency. | 10-02-2014 |
Patent application number | Description | Published |
20110311701 | RIGID DURABLE NON-METALLIC RELEASE LAMINATE FOR OVEN COOKING AND OVEN CONTAINING SAME - A rigid, durable non-metallic release laminate for holding food products during baking, cooking, toasting and other processing is provided. By eliminating the use of metal, the laminate of the invention can be readily manufactured in a variety of shapes and forms. The laminate can be used in a wide variety of ovens, including without limitation a conventional baking oven, microwave oven, toaster oven, convection oven, or multi-technology oven. | 12-22-2011 |
20120085880 | FOOTING FOR BOAT COVER SUPPORT - A footing for a support, such as a pole. The footing includes a generally flat and flexible base, a support receiver formed on the base, and a slit through the base and extending inwardly toward the support receiver from an outer edge of the base. | 04-12-2012 |
20130240333 | FLEXIBLE CONVEYOR BELT WRAPPER - A flexible composite conveyor belt, such as for use as a belt wrapper in overlying combination with a metal belt in cooking or heating operations. The belt includes a protrusion attached to a flexible substrate. The protrusion includes an engagement surface adapted to secure the protrusion to a portion of the underlying metal belt to drive the belt at a same speed as the conveyor belt. Protrusions on opposing ends of the belt negate the need for conventional lacing in securing the ends of the belt together. | 09-19-2013 |
20130277374 | COOKING SUPPORT WITH REMOVABLE MESH INSERT - A food support for holding food items during cooking in an oven. The food support includes a reinforcement structure including a perimeter frame extending around and defining a substrate placement area. At least one cross bar extends between two opposing portions of the support frame and beneath the substrate placement area. A removable and replaceable substrate insert is sized to be placed on the substrate placement area for receiving food items thereon. A securing element can be connected to the reinforcement structure for securing the substrate insert on the substrate placement area. A holding device including a holding surface connected to a clamping element, where the holding surface is adapted to support a bottom of the food support and the clamping element is adapted to clamp over a top surface of the food support, can be used to securely introduce and/or remove the food support from an oven. | 10-24-2013 |
