Publication number: 20230051106Abstract: Embodiments are generally directed to systems and apparatuses for tracking usage of an item. For example, an apparatus may be provided for tracking use of a packetized item. The apparatus may include a microprocessor, a power source, and a structural layer to which the microprocessor and power source are coupled. The structural layer may include a container that is configured to hold various items. The container may also include an opening that allows access to the items. The apparatus may further include a cover layer that is configured to cover the opening of the container. The cover layer may include at least one bendable sensor placed over the opening of the container. The microprocessor may be configured to determine, using detected movements in the bendable sensor, whether the container has been opened.Type: ApplicationFiled: October 31, 2022Publication date: February 16, 2023Inventors: Michael Osborne Isom, Duane Michael Scott Johnson, Lance Squire, Joseph Arthur Harris, David Brewster Beck

Publication number: 20200296514Abstract: Disclosed herein is an audio system having servo-controlled audio speaker and an amplifier. Interposed between the audio speaker and the amplifier is a feedback circuit configured to provide a feedback signal to the amplifier regarding errors and distortions in the operation of the speaker. The feedback circuit includes a flexible sensor connected to the speaker diaphragm and the frame of the speaker. The flexible sensor changes its resistance responsive to changes in its shape. The feedback signal is used by the amplifier to apply corrections to the drive signal for the audio speaker.Type: ApplicationFiled: March 13, 2019Publication date: September 17, 2020Applicant: Subvo LLCInventors: Joseph Arthur Harris, David Brewster Beck

Patent number: 9705597Abstract: Techniques for communicating lighting commands through a controller area network (CAN) bus of a light bar system include generating a light code message. The light code message has a metadata portion and a value portion. The metadata portion defines a purpose of value portion. The value portion controls a state of a lighting device (e.g., a keypad's LED brightness or activation of a directional light module) in the light bar system. A data field is generated by encapsulating the light code message with an ISO-TP single frame header and a message subtype. A CAN controller generates a CAN message having an extended frame format and the data field. The CAN message is then transmitted through the CAN bus.Type: GrantFiled: August 12, 2016Date of Patent: July 11, 2017Assignee: Electronic Controls CompanyInventors: Mark W. Latham, William M. Cresse, Kevin David Brewster

Patent number: 7695686Abstract: Sample preparation device and method for desalting and concentrating samples prior to further analysis such as by MALDI TOF and/or electro-spray ionization (ESI) mass spectrometry. The device in accordance with an embodiment of the present invention contains a three dimensional structure preferably comprising a plurality of sorptive particles entrapped in a porous polymer matrix so as to form a device capable of carrying out solid phase extraction. The device is manufactured by introducing casting solution containing polymer and optionally particles into a housing, and subsequently exposing the device to a quench bath for a time sufficient to allow for solvent exchange and precipitation to form the composite structure in the housing. The present invention is also directed towards a method of sample preparation using the device of the present invention.Type: GrantFiled: December 9, 2004Date of Patent: April 13, 2010Assignee: Millipore CorporationInventors: William Kopaciewicz, Phillip Clark, David Brewster
