Publication number: 20200171219Abstract: Embodiments of negative pressure wound therapy systems and methods for operating the systems are disclosed. In some embodiments, a system includes a pump assembly, canister, and a wound dressing configured to be positioned over a wound. The pump assembly, canister, and wound dressing can be fluidically connected to facilitate delivery of negative pressure to the wound. The system can be configured to deliver negative pressure based at least on a sensed pressured in a fluid flow path connecting a pump of the pump assembly and the wound dressing. The sensed pressure can be sampled, in some embodiments, synchronous with operation of the pump and can be used for controlling the pump. Increased efficiency, diminished noise and vibration caused by operation of the pump, reduced in energy usage, and better comfort for the patient can be attained.Type: ApplicationFiled: February 7, 2020Publication date: June 4, 2020Inventors: Raymond Carr, William W.

Publication number: 20170347940Abstract: The disclosure describes a smart bandage assembly. The bandage assembly includes a bandage member; a movement sensor, a pressure sensor, a methane sensor, or a humidity sensor; a microcontroller; a memory; and a radio transceiver for communication with a mobile communications device. The electronic components of the bandage assembly may be embedded within the bandage member. In some implementations, the radio transceiver harvests RF energy to power the memory within the bandage assembly so that sensor data stored in the memory can be accessed by a mobile communications device when other remaining electronic devices in the bandage assembly remain in a sleep state or power off mode.Type: ApplicationFiled: June 6, 2017Publication date: December 7, 2017Inventor: Raymond A.

Patent number: 8188408Abstract: A conveyorized oven that provides uniform cooking with control of the heater and/or the conveyor belt speed. The oven includes a controller that monitors power consumption of the heater and uses the power consumption to control the heater and/or the speed of the motor that drives the conveyor belt. The power consumption is monitored by counting the on time cycles of a switch that connects and disconnects the heater to a power main. Changes in the power consumption due to changes in loading are used by the controller to reduce recovery times of the oven temperature to a set temperature by controlling the heater and/or the motor. By using a stepper motor, there is no need for a gear box.Type: GrantFiled: March 14, 2008Date of Patent: May 29, 2012Assignee: Enodis CorporationInventors: Jan Claesson, Raymond Carr, Roberto Nevarez

Patent number: 6140793Abstract: A low overhead controller for microstepping a stepper motor and a low overhead method for microstepping a stepper motor. The reduction in overhead in system processor is accomplished by the control circuit which dynamically interpolates motor positions between steps commanded from the processor. Also, the reduction in overhead is accomplished by a microstepping method used to effect microstepping resolution control by employing a stored look-up table which gives a resolution value at a given speed according to a predetermined function.Type: GrantFiled: August 19, 1999Date of Patent: October 31, 2000Assignee: Bristol-Myers Squibb CompanyInventors: Raymond A.

Patent number: 6038914Abstract: A leak sensor system for use in liquid processing equipment is disclosed. Liquid is detected by a sensing resistor whose impedance decreases dramatically in the presence of liquid. The effect of this impedance drop on the output voltage of he sensor indicates a wet or moist state which may indicate leakage from the liquid processing. A terminal resistor is in the circuit beyond the sensing resistor ro provide a warning indicator when the sensing resistor is damage or disconnected. The leak sensor system is particularly useful in centrifuge equipment, e.g., for the processing of blood.Type: GrantFiled: February 27, 1998Date of Patent: March 21, 2000Assignee: Bristol-Myers Squibb CompanyInventors: Raymond A.

Patent number: 5712460Abstract: A multi-function control system to control a variety of operations associated with a powered surgical device such as an arthroscopic surgical shaver. The system has an ergonomically designed foot switch which has a plurality of discrete force sensitive transducers arranged in an arcuate pattern. The transducers have no moving parts and have a force sensitive element which produces a variable output which is a function of the force applied by a user. The foot switch is used in conjunction with a control console which enables a user to adjust the force sensitivity threshold of the transducers. The foot switch additionally has physically discrete and tactilely sensible areas enabling a user to activate selected functions with a minimal amount of foot movement.Type: GrantFiled: September 17, 1996Date of Patent: January 27, 1998Assignee: Linvatec CorporationInventors: Raymond A.
