A device and a method are provided for determining a characteristic of an interchangeable component of a surgical instrument. An electrically conductive material having a measurable strength measurable by a hall effect sensor is coupled to the component. In another embodiment, a plurality of conductive materials are arranged to form a binary code representing a corresponding of the interchangeable component. The number and / or strength of the magnets measurable by the sensors may be dynamically altered such that the status of the surgical instrument is determinable.

A high strength porous biphasic polymeric reinforcement material manufactured by a compression and / or sintering process is disclosed. The material results in a network of interconnected collapsed pores, which forces thin overlapping walls and passages to be created. The network provides permeable access for fluid migration throughout the material. The strength and / or permeability are advantageous for medical devices and implants.

Soft, durable and bulky tissue products comprising non-wood fibers and more particularly high yield hesperaloe pulp fibers are disclosed. The tissue products preferably comprise at least about 5 percent, by weight of the product, high yield hesperaloe pulp fiber and have relatively modest tensile strengths, such as a geometric mean tensile (GMT) less than about 1,000 g / 3″, and improved durability and cross-machine direction (CD) properties, such as a CD Stretch greater than about 10 percent. Additionally, at the foregoing tensile strengths the products are not overly stiff. For example the tissue products may have a Stiffness Index less than about 10.0.

An implantable biosensor assembly and system includes an enzymatic sensor probe from which subcutaneous and interstitial glucose levels may be inferred. The assembly may be associated by direct percutaneous connection with electronics, such as for signal amplification, sensor polarization, and data download, manipulation, display, and storage. The biosensor comprises a miniature probe characterized by lateral flexibility and tensile strength and has large electrode surface area for increased sensitivity. Irritation of tissues surrounding the probe is minimized due to ease of flexibility and small cross section of the sensor. Foreign body reaction is diminished due to a microscopically rough porous probe surface.

A mirror assembly for a vehicle includes a mirror element having at least one substrate that has a forward surface and a rearward surface. The mirror element comprises at least one substantially reflective metallic layer sandwiched between a respective pair of substantially transparent non-metallic layers. Each of the substantially transparent non-metallic layers and the substantially reflective metallic layer have a selected refractive index and a selected physical thickness such that the reflective element is selectively spectrally tuned to substantially transmit at least one preselected spectral band of radiant energy therethrough while substantially reflecting other radiant energy. A radiant energy emitting element is disposed at or near the rearward surface of the at least one substrate. The radiant energy emitting element is configured to emit radiant energy with a peak intensity within the at least one preselected spectral band.

A suture anchor includes a body having a distal end and a proximal end. Projections in the form of ribs or threads are formed on the body for retaining the anchor in a hole formed in bone. An eyelet formed on the distal end of the body accepts suture. The eyelet preferably is formed by a loop of suture. Where the body of the anchor is formed of a polymer, the suture loop can be formed by insert-molding the suture into the body. Tissue is reattached to bone using the suture anchor by securing a length of suture to the tissue, and threading the length of suture through the eyelet on the distal end of the anchor, leaving lengths of suture extending from either side of the eyelet. Installing the suture anchor into the bone wedges the lengths of suture between the suture anchor and the bone, thereby securing the tissue without the need for tying knots. Pullout strength can be enhanced by twisting the lengths of suture prior to installation of the anchor into the bone.

Disclosed is a polycrystalline diamond or diamond-like element with greatly improved wear resistance without loss of impact strength. These elements are formed with a binder-catalyzing material in a high-temperature, high-pressure (HTHP) process. The PCD element has a body with a plurality of bonded diamond or diamond-like crystals forming a continuous diamond matrix that has a diamond volume density greater than 85%. Interstices among the diamond crystals form a continuous interstitial matrix containing a catalyzing material. The diamond matrix table is formed and integrally bonded with a metallic substrate containing the catalyzing material during the HTHP process. The diamond matrix body has a working surface, where a first portion of the interstitial matrix in the body adjacent to the working surface is substantially free of the catalyzing material, and a second portion of the interstitial matrix in the body adjacent to the working surface contains the catalyzing material. The first portion of the interstitial matrix and the second portion of the interstitial matrix have substantially the same impact strength.

Embodiments of the invention relate generally to an ultraviolet (UV) cure chamber for curing a dielectric material disposed on a substrate and to methods of curing dielectric materials using UV radiation. A substrate processing tool according to one embodiment comprises a body defining a substrate processing region; a substrate support adapted to support a substrate within the substrate processing region; an ultraviolet radiation lamp spaced apart from the substrate support, the lamp configured to transmit ultraviolet radiation to a substrate positioned on the substrate support; and a motor operatively coupled to rotate at least one of the ultraviolet radiation lamp or substrate support at least 180 degrees relative to each other. The substrate processing tool may further comprise one or more reflectors adapted to generate a flood pattern of ultraviolet radiation over the substrate that has complementary high and low intensity areas which combine to generate a substantially uniform irradiance pattern if rotated. Other embodiments are also disclosed.
