Abstract: An automatically-opening infant mat that is movable between an open position and a closed position includes a water-resistant flexible material sized to have an infant, at least from the infant's head to the infant's buttocks, placed on the material while the mat is in the open position, a cushion coupled to the material to be disposed under a portion of the infant's body while the mat is in the open position and the infant is placed on the material, and a resilient bias member coupled to the material and configured to bias the material to an open position and to be reversibly moved to a closed position.

Abstract: A sun shade for use with and mounting to a side or rear automobile window includes a material comfigured to inhibit sunlight from passing through the material while allowing sufficient light to pass through the material such that a person can see through the material, and a temperature indicator coupled to the material and configured to provide a visible indication of temperature, where the sun shade is configured to attach to the side or rear automobile window.

Abstract: The present invention discloses a methodology for the characterization and determination of mixed-field dosimetry for 252Cf Applicator Tube (AT)-type medical sources, utilizing ionization chambers, GM counters, and Monte Carlo methods. Unlike the previous methodologies, the present invention discloses a specification of dose to muscle, rather than dose to water, for clinical dosimetry of 252Cf medical sources. A dosimetry protocol, similar to that utilized for ICRU-45, with parameters determined specifically for 252Cf brachytherapy is disclosed. Neutron isodose distributions and data necessary for clinical implementation of 252Cf AT sources are also disclosed herein. Additionally, novel methods for the encapsulation, storage, and delivery/implantation of 252Cf radionuclide sources are disclosed.

Abstract: A communication bus interface circuit includes a local frame signal generator responsive to a device clock signal and having a local bus frame signal output. A synchronization loss detector is responsive to the local frame signal output and to a bus frame signal input. A clock adjuster is responsive to the synchronization loss detector and to the device clock signal to adjust the local frame signal generator until synchronization between the bus frame signal and the local frame signal is established.
