摘要:
A surgical penetration instrument has an elongated shaft and a penetrating tip extending from the distal end of the shaft. A blade extends outwardly from the penetrating tip. The blade is transparent. When the penetrating tip is transparent, the tip not only facilitates penetration through bodily tissue but also acts as an imaging element in conjunction with an endoscope extending through the shaft of the instrument to simultaneously visualize the surgical field during penetration. Significantly, unlike a conventional metallic blade, the transparent blade will not obstruct the field of view as the instrument is advanced. When the penetrating tip is plastic, and the blade is composed of a transparent plastic, the blade can be joined to the tip using conventional plastic processing methods such as injection molding, thus reducing manufacturing costs incurred if a metallic blade were used. Also disclosed is a surgical penetration instrument with a plastic penetrating tip and a protective cap fitting over and enclosing a portion of the tip to prevent or lessen the possibility of breaking, cracking or otherwise damaging the tip.

A method for providing real time indicator of voice transmission quality in a Voice over Internet Protocol (VoIP) network is disclosed. The method allows to receive, at regular time interval during a call, a digital signature from a source call device. The received signature is compared to a referential signature stored on the destination devices, and in case the received signature falls out of the referential signature, a quality indication message is transmitted back to the source call device.

Disclosed are compounds of the formula: where variables Z, X, R15, R2, R3, and Rc are defined herein. Compounds disclosed herein are inhibitors of the beta-secretase enzyme and are therefore useful in the treatment of Alzheimer's disease and other diseases characterized by deposition of A beta peptide in a mammal.
摘要:
An interactive multimedia presentation has a predetermined presentation play duration, a video content component (which may include video, audio, data, or any combination thereof), and an interactive content component. Methods and systems for playing the presentation include specifying a time when a particular media object is renderable. The time is specifiable using an application instruction that references either a first timing signal having a rate that is based on the play speed of the presentation, or a second timing signal having a continuous rate. One example of an application instruction usable as described above is an element associated with an XML data structure. An attribute of the element, such as the clock attribute, may be used to provide time values for the element that reference either timing signal. The attribute is used to maintain frame-accurate synchronization between the video and the interactive content components of the presentation.
摘要:
A display cabinet includes a fiber optic cable having a first fiber optic cable portion introduced into a raceway of a door frame which is divided into fiber optic cable groups each exiting the raceway and being connected to light distributors located along vertical mullions/end frame members of the door frame to illuminate an interior area of the cabinet and products therein. Terminal end portions of individual fiber optic elements of each group are fastened relative to light-emitting holes of individual light distributors. Each light distributor includes a pair of wall portions at opposite sides of a bisecting plane of the light distributor with the light-emitting holes on either side being disposed with axes thereof at two acute though substantially different angles. A pair of ribs at a rear side of the light distributor effect reinforcement thereof and cooperate to fasten terminal ends of each fiber optic element thereto.
