  • Patent number: 10772293
    Abstract: Systems and methods provide automated data collection of feed behavior and intake for animals in confinement where the animal ingests feed from a feed station that includes a first and second feed container each of which holds a feed that is freely accessible to the animal, and a respective first and second weight sensor each of which senses a change in weight of the respective feed in the container. A processor is configured to transmit instructions to cause it to receive from the weight sensors, a plurality signals indicative of a change in weight in the first and second feed containers. The processor records a reduction in weight sensed by the first or the second sensor as consumption of the respective feed, and records a change in weight sensed by the first or the second sensor as feeding activity at the respective feed container.

  • Publication number: 20110016377
    Abstract: A system and method for incident reporting uses an application server on a network to facilitate the creation of incident reports and distribution of the reports for review, and controls access to the incident reports to protect the integrity and confidentiality of the reports. Each incident report is given a routing profile, which is tailored such that only proper authorized persons can review and/or edit the report. The progress of incident report review and incident investigation is tracked, and the tracking data are stored for monitoring and auditing purposes. Access to selected reports may be given to users on a temporary basis. The incident reports are archived to enable auditing and generation of reports.

  • Publication number: 20050130103
    Abstract: A reduction burr for universal application for depth reduction of dental or ossiferous surfaces includes a shank of a first diameter extended to a chamfered rim angled radially inwardly to a smaller second diameter. A curved shoulder extended from the chamfered rim decreases in cross-sectional diameter to a distal end having a third diameter. A burr end having an abrasive surface thereon is extended from a junction with the shoulder distal end to a distal burr end, with the abrasive surface having sufficient hardness to cut enamel or ossiferous surfaces. The junction defines a precise stop for self-limiting the burr penetration depth into the enamel or ossiferous surfaces due to the greater second diameter of the curved shoulder contacting against adjacent uncut surfaces. A method of size reduction is disclosed for universal application of a reduction burr to precisely reduce enamel or ossiferous surfaces in both lateral and longitudinal directions.

  • Publication number: 20050092551
    Abstract: A coupling member for securing a ladder base end positionable against an unstable or uneven supporting surface. The coupling member includes a pair of receiving members disposed parallel and spaced apart for positioning the ladder base end thereupon and proximal of the supporting surface. A stabilizing cross-member extends between inner walls of the receiving members and is slidably adjustable in a width dimension to span a variety of ladder base widths. Outboard of each receiving member is disposed a side sleeve having an axially oriented channel therethrough in which a fixation member is slidably inserted to extend a contacting end against the supporting surface. Each fixation member is adjustable in height relative to respective side sleeves, thereby allowing the coupling member to be adjusted in a level orientation proximal the supporting surface with stabilization of the ladder base ends restrained in respective receiving members during load-bearing activity on the ladder.

  • Patent number: 6465235
    Abstract: Novel carbonyl hydrolase mutants derived from the amino acid sequence of naturally-occurring or recombinant non-human carbonyl hydrolases and DNA sequences encoding the same. The mutant carbonyl hydrolases, in general, are obtained by in vitro modification of a precursor DNA sequence encoding the naturally-occurring or recombinant carbonyl hydrolase to encode the substitution, insertion or deletion of one or more amino acids in the amino acid sequence of a precursor carbonyl hydrolase. Such mutants have one or more properties which are different than the same property of the precursor hydrolase.
