The proposed meniscus suturing machine provides quick, strong, reliable sutures to torn medial menisci. An electronically controlled pneumatic system powers the suturing process. The meniscus suturing machine utilizes the chain stitch, a common sewing stitch, and applies it to the repair of torn menisci using only a single thread. The designed device is simple to use, with an on/off switch and fire button. While the device is simple, it has internal fault protection devices such as an automatic emergency shutoff and suture recovery loop. The device also comes apart easily, with a disposable needle-thread system. An autoclave sterilizes the remaining portion of the device. The initial application of the design is to suture medial menisci, but modifications will allow the suturing device to accommodate other areas too, such as the lateral meniscus. The benefits of the suturing device include a reduction in operating time and complexity of meniscus repairs.

A reclining chair assembly includes a reclining chair that has a backrest portion and a chair portion for having a user sit therein. A pair of footrests is each disposed on the chair portion of the reclining chair and each of the footrests is positionable in a lowered position or a raised position to raise the respective user's leg. Moreover, the pair of footrests is independently positionable in the raised position to facilitate one of the user's legs to be lifted while the other of the user's legs is not lifted. A pair of lifting units is each in mechanical communication with a respective one of the pair of footrests. Each of the lifting units independently urges the respective footrest into the raised position or the lowered position.

Commonly, a transient protection filter circuit is integrated between power sources and the circuits that follow to suppress voltage transients. Pre-existing transient protection filters are implemented such that when a transient is detected, transistors in the path become linear regulators. Instead, this invention uses bridge resistors to form a voltage divider to dissipate the extra power. The novelty of this invention is that it protects the load not by dissipating the extra power in front of the load as other transient protection filter circuits do, but by providing energy from the transient to the load through a resistor. This implementation solves the problem of thermal runaway that is commonly caused when transient voltages are filtered by dissipating power within the transistors in the path of the transient and the electric circuits after the transistors.

A prefabricated wall panel has a precast body including at least one decorative design element. In addition, the wall panel includes a mounting element having a first end embedded in the precast body and a second end projecting from the precast body. A groove is formed between the precast body and the second end of the mounting element along a first edge of the precast body. A tongue is formed along a second edge of the precast body opposite the first edge. The tongue and groove cooperate to allow prefabricated wall panels to be more easily installed on a support substrate.

A method and system for font building by providing for the downloading of a subset of glyphs at a client device from a server. The subset can include one or more particular requested glyphs. The subset is accompanied by one or more further glyphs determined by selection criteria, which can include: frequency of use of the glyphs in a particular language; frequency of use of the glyphs by at least one client device; and relationships between particular glyphs.

One aspect of the invention provides an ingress apparatus comprising a signal processing apparatus for receiving an incoming data frame and locating the position of path overhead, and a monitoring apparatus arranged to extract information from the located path overhead. The ingress apparatus further includes an insertion apparatus for receiving, from the monitoring apparatus, information extracted from the path overhead of one or more signal path, and being further arranged to insert the extracted information into a respective data frame component which occupies a fixed position in a data frame. Thus, information which would normally occupy a non-fixed position in a data frame is moved to a fixed position. As a result, the information can subsequently be accessed without having to employ relatively complex apparatus for locating information which occupies a non-fixed position.
