Abstract: Various systems, devices and methods are provided for interconnection between wafers and/or chips using catch flexures. In one example, among others, a catch flexure assembly includes a first interconnect affixed to a first wafer. The first interconnect can include a female opening at a distal end of a flexible member that is configured to receive a male extension of a second interconnect affixed to a second wafer when the first wafer is aligned with the second wafer, and retain the male extension during a bonding process of the first and second flexible interconnects. The catch flexure assembly can also include bonding material disposed adjacent to the female opening, which is configured to secure the male extension in the female opening during the bonding process.

Abstract: The present disclosure relates generally to writing and reading data from a magnetic tape storage media and, more particularly, to a secure erasure system for the eradication of the data contained in the data tracks of a tape media such that substantially all of the data can be erased while leaving the servo bands substantially unaltered or within specification. A data tape cartridge erased with such a system can then be reused in a secure data storage environment with complete confidence that any data from a previous usage is not subject to discovery.

Abstract: A mild inexpensive process for treating lignocellulosic biomass involves oxidative delignification of wood using an aqueous solution prepared by dissolving a catalytic amount of manganese (III) acetate into water and adding hydrogen peroxide. Within 4 days and without agitation, the solution was used to convert poplar wood sections into a fine powder-like delignified, cellulose rich materials that included individual wood cells.

Abstract: The present disclosure relates to apparatus and methods for recording heads with tape guides, including embedded tape guides. In one embodiment a magnetic recording head includes a contour modified to include a tape guide. The tape guide may include compliant or non-compliant edge guides. In another embodiment, a magnetic recording head includes a contour configured to impart a lateral force on the surface of tape streaming over the head. The head may include air-bleed slots, air skiving edges, non-symmetrical head surfaces, specific contour topographies, negative pressure elements, or any combination thereof. The streaming tape may be held referenced against the a tape guide by the lateral force. In a further embodiment, the present disclosure relates to magnetic tape wherein the written-in lateral tape motion is substantially eliminated.

Abstract: A glove or apparel formed at least partially from a knitted thread substrate and including areas on an outer surface which has a substantially continuous surface surrounding ends of the finger portions and thumb portion of the glove and areas which have a substantially non-continuous surface positioned over the palm portion and the back of the hand portion of the glove.

Abstract: The present disclosure relates to a magnetic recording head having a slider media bearing interface surface with surface modifications configured to reduce friction and/or stiction friction properties between the head slider media bearing interface surface and a recording medium. The present disclosure also relates to a tape drive system, a method of formatting a recording medium using such a magnetic recording head, and the resulting formatted media.

Abstract: The present disclosure relates to the minimization of servo format transition bit length of magnetic recording media. More particularly, the present disclosure relates to bi-polar and trailing edge recording when formatting the servo track of magnetic recording media. In one embodiment, magnetic media having a timing-based pattern is written using a bi-polar energized recording head. In some embodiments, the magnetic media may be AC or DC erased. The recording head may include a plurality of independent recording channels, each of which may be magnetically energized individually. The bi-polar energized state of the recording head may be controlled to vary the bit length and bit sequence within the timing-based pattern. In further embodiments, the magnetic media may include both uni-polar and bi-polar transitions.

Abstract: The present invention is system and method for providing a self-calibrating pressure sensor. A pressure sensor apparatus comprises a diaphragm, at least one driving element operably coupled to the diaphragm configured to induce deflection in the diaphragm, and at least one strain gauge coupled to the diaphragm. The at least one strain gauge measures the deflection of the diaphragm. Typically, the driving elements will be piezoelectric drivers and will be operably coupled to the diaphragm. A method for evaluating a pressure sensor comprises inducing deflection in a diaphragm, measuring the deflection, determining the frequency-dependent response, calculating mechanical characteristics of the diaphragm from the frequency-dependent response, and calculating a response coefficient for the diaphragm based in part on said mechanical characteristics. The response coefficient is used to evaluate the sensor. The sensor can then be re-calibrated or self-calibrated based on the response coefficient.

Abstract: A sub-circuit based extraction method which extracts a multi-finger MOS transistor directly as a sub-circuit is described. By adding three marking layers, the method provides the layout extracted netlist with a complete list of device geometric parameters corresponding to the device properties as presented in the sub-circuit model based schematic netlist. By performing a layout-versus-schematic comparison based on all geometric parameters extracted, the layout checking is performed in a complete and accurate way where each device parameter is checked against the corresponding design schematic. This complete and accurate geometric parameter comparison enhances the confidence level of the layout physical verification.

Abstract: An eye protection arrangement for protection against multispectral laser threats includes goggles or spectacles with a tunable etalon optical filter. In one embodiment, the optical filter is fixed-tuned to a safe frequency. In another embodiment, light from the laser being used is sensed, and used to set the protective goggles to a different wavelength than the laser. In yet another embodiment of the invention, the protective optical filters have a comb response, and additional protection is provided by optically cascading two filters, each having a somewhat different comb response, so as to reduce the number of transmission spectra.

Abstract: A two-way light amplitude divider includes a light rotator (18) with first (18.sub.1), second (18.sub.2) and third (18.sub.3) ports. The second port is coupled to a port of a controllable Fabry-Perot etalon (22). The etalon can take on a state in which a particular .lambda. of light is passed, and others are reflected. Light at .lambda..sub.1 applied to the first port (18.sub.1) of the rotator (18) passes through the etalon (22) to a port (22.sub.2) when the etalon (22) is in its first state, and the light is reflected by the etalon (22) in its second state, and flows to the third port (18.sub.3) of the rotator (18). Thus, the arrangement (10) acts as a single-pole, double throw switch, depending upon the state of the etalon. The arrangement can be cascaded in a manner which operates as a multiplexer (700) or demultiplexer (600).
