Abstract: A surgical device (100) for guiding a key wire during a shoulder arthroplasty procedure, comprising a guide (105) for guiding a key wire (160) during the process of drilling into a scapula, and clamp means (101) configured to engage with the scapula neck such that a key wire located in the guide is located in a predetermined geometrical relationship with the scapula neck.

Abstract: An optical system for remotely optical communications at a high data rate between a base station and a remote station under atmospheric turbulence conditions is disclosed. The remote station includes an entirely different type of retroreflector that does not use the conventional type of retroreflection, but instead consists of two sets of lenslets coupled with single-mode fiber array, called fiber “retro”. Amplified retromodulation is achieved requiring only one single optical amplifier and one single modulator. A transmitter located at the base station sends an interrogating optical beam to the fiber “retro” which modulates the optical beam according to the input signal/data, and redirects the modulated optical beam to the base station for detection by a receiver. The present invention includes the capabilities of providing Identification of Friend-or-Foe (IFF), secure communication, and a means of achieving a wide field-of-view (FOV) with a fiber-coupled lenselet array.

Abstract: The present invention relates to a process for reducing residuals content in a vinyl aromatic polymer, said residuals comprising essentially unpolymerized vinyl aromatic monomer, wherein the vinyl aromatic polymer in the molten state is brought in contact with a solid in powder capable to catalyze the alkylation of said residual vinyl aromatic monomer on the vinyl aromatic polymer. Advantage of the present invention is a sharp reduction of the unpolymerized vinyl aromatic monomer in the vinyl aromatic polymer without generating a new residual and without inducing a colored vinyl aromatic polymer. The present invention also relates to said vinyl aromatic polymer having a low residuals content.

Abstract: A real estate security device for controlling access to premises by realtors. A housing having a shackle lock is removably locked to a door handle of the premises. A barrier precludes access to the shackle from an interior of the housing. A portal communicates the housing interior with an area outside through a sliding door. A door lock independent from the shackle lock opens the door to the housing to allow access to contents of the interior where a premises key can be located when the premises' owner wishes to allow access to the premises.

Abstract: A key safe having a shackle to secure the key safe to a door knob or the like and a first locking means associated with the shackle to allow installation and removal of the key safe. The key safe has an interior chamber accessed through a removable cover secured by a second locking means independent of the first locking means. Thus the owner or occupant of a premises can provide limited access to the premises for a real estate agent or other authorized person by installing the key safe on the exterior of a door to the premises with a key to the premises contained therein.
