Abstract: A method of tinting or coloring glass. The following layers are deposited onto the glass: a first dielectric layer, a subcritical metallic layer; a primer layer; and a second dielectric layer. Alternatively, these layers may be deposited onto the glass: a first dielectric layer, a subcritical metallic layer; and a second dielectric layer. Alternatively, the invention is a coated article that includes a substrate, a first dielectric layer, an absorbing layer, and a second dielectric layer over the primer layer. The absorbing layer can be Inconel, titanium nitride, cobalt chrome (stellite), or nickel chrome material, and has a thickness in the range of 50 ? to 150 ?.

Abstract: The present disclosure relates to prosthesis systems having trays and liners having an asymmetrical locking mechanism to bias the strength of the liner to resist loading forces and associated methods. The tray has a lateral groove disposed in an inner surface of a lateral circumferential portion of the tray and a medial groove disposed in an inner surface of a medial circumferential portion of the tray. The liner has an upper segment and a lower segment. The liner has a locking portion for lockingly engaging the tray that includes the lower segment. The locking portion has a lateral toe positioned generally diametrically opposite a plurality of resiliently deformable medial fingers defined therein. The liner and the tray are engageable in a lateral-to-medial direction so that the plurality of medial fingers can resiliently deform to engage the medial groove subsequent to engagement of the lateral toe within the lateral groove.

Abstract: Radio Frequency Identification (RFID) antennas systems and methods that are less sensitive to orientation. One example includes an interrogator having a radio frequency transceiver, a first linearly polarized antenna in electrical communication with the transceiver, and a second linearly polarized antenna in electrical communication with the transceiver, the second antenna having a polarization in a direction substantially perpendicular to the first antenna; a control circuit is in electrical communication with the transceiver and with the first and second antennas, the control circuit operable to switch between interrogating with the first antenna and interrogating with the second antenna, and an RFID decoder is coupled to an output of the transceiver to decode an interrogated electromagnetic signal from a tag.

Abstract: Disclosed are embodiments of methods, systems, and apparatus for ranging or determining a distance between a reader and a wireless tag. In one embodiment, a query signal is transmitted from the reader to the wireless tag. The carrier signal from the reader may then be modulated and the modulated signal transmitted from the reader during at least a portion of a response period for the wireless tag. A modulated backscatter response from the wireless tag is received at the reader and is used to calculate a distance between the reader and the wireless tag.
