Abstract: A pipe standing adapter is a device designed for placement on a round pipe to create a flat surface. An interrupting flange, offset from a center and extending parallel to a length of a pipe (between locations about semi-circular openings for a pipe) is on the otherwise flat surface designed for a base of a ladder to be abutted there-against. An acutely angled ladder can then be placed against the interrupting flange and a worker can climb down the ladder safely on to the platform which rests on the pipe.

Abstract: Pilates reformers, and exercise apparatus, are widely used by individuals of varying levels of fitness. The moveable carriage of the reformer onto which the person is to lie supine during exercise is difficult to mount for some individuals, such as the elderly or pregnant women. A replacement for the planar one-piece carriage is disclosed that is a two-piece platform having a seat portion and a back portion that pivots with respect to the seat portion. The individual can mount the exercise apparatus on the seat portion with the inclined back portion for support. The back portion can then be lowered to a completely horizontal position or slightly inclined, depending on the needs of the individual. An articulated platform has an extendible gas spring mounted between the back portion and a support structure. The gas spring assists the individual, or a trainer, to move the back portion up.

Abstract: A computer-implemented method and system are provided for authenticating the identity of a user registered with a computer system. The authentication method comprises generating a multi-dimensional array of elements that are addressable by respective sets of indices, generating a challenge code comprising a linear array of elements for addressing a first set of indices of the array of elements, transmitting the multi-dimensional array of elements and challenge code to at least one computing device associated with the user, receiving a response code from the user, and verifying the user's identity when the received response code matches a derived code obtained by retrieving elements from the multi-dimensional array at locations addressed by elements taken from the challenge code and a personal code stored at the computer system, wherein the personal code comprises a linear array of elements for addressing a different set of indices of the array of elements.

Abstract: The invention relates to casings for portable communication devices. The casing is reusable with engines having different processing capabilities.

Abstract: An apparatus and method for sensing chemical and/or biological analytes includes a deflectable arm of a microcantilever at least partially embedded within a sensing element. A gaseous or liquid medium which may include the analyte being detected is introduced to the sensing element. The sensing element undergoes volumetric expansion or contraction in the presence of the analyte sought to be detected, typically by adsorbing the analyte. The volumetric change of the sensing element causes the deflectable arm to deflect. The deflectable arm includes at least one measurable physical property which changes when the arm deflects. Detecting means are provided to measure the change in the physical property to determine the presence and amount of analyte present. An array of microcantilevers in which each microcantilever is dedicated to detecting a particular analyte which may be included in the medium, is also provided.
