Patent CA-2194315-A1 (CA)
Title: Compliant support pad
Inventor: PACIA ED
IPC: G06F3/02
Filed: 1997-01-03
Abstract: A slender pad for supporting portions of the human body contains a fluid layer within a flexible cover, permitting local accommodation of the pad in supporting relation with the body. In a preferred embodiment the fluid is a gas such as air, preferably contained within an impermeable sheath to permit at least local deformation of the sheath under localized loads. One use for the pad is asa wrist support for users of computer keyboards and the like, wherein the sensitivity of the pad in conforming with the form of the users wrist, serves toavoid the generation of localized pressure points, to thereby promote natural functioning of wrist in cooperation with the movements of the user's fingers on the keyboard. One construction of the subject pad incorporates air bubbles contained within a plastic sheath, having a cloth overlay in protective, conforming relation to preserve the flexibility of the pad surface while also protecting the plastic bubble sheath against undue wear. Also, an intermediate, highly flexible, thin load transfer layer such as foam plastic can be laminated to the bubble sheath. The shape of the pad plan profile may be conformed to the shape of the front edge of the respective keyboard, so that the pad can be positioned in closer proximity, for the convenience of the user. Adherent patches such as those trade marked "Velcro" may be provided, for attaching the pad to the keyboard.

Title: Self-phase up of array antennas with non-uniform element mutual coupling and arbitrary lattice orientations
Inventor: BOE ERIC
IPC: G01R29/10
Filed: 1997-04-29
Abstract: A technique for phase-up of array antennas of regularly spaced lattice orientation, without the use of a near-field or farfield range.  The technique uses mutual coupling and/or reflections to provide a signal  from one element to its neighbors.  This signal provides a reference to allow for elements to be phased with respect to each other.  After the first stage of the process is completed, the array is phased-up into,  at most,  four interleaved lattices.  These interleaved lattices are then phased with respect to each other, thus completing the phase-up process.

Title: Toilet seat apparatus
Inventor: DIAS ARNALDO DAS NEVES
IPC: A47K13/10
Filed: 1997-10-03
Abstract: Apparatus for raising and lowering a pivoting toilet member mounted on top of a toilet bowl that is part of a flushing toilet equipped with a water tank.  Apparatus includes first and second weights, the first weight being connectible to the toilet member and provided to raise the toilet member, the second weight being adapted for mounting in the water tank and provided to lower the toilet member.  The second weight is connected to the toilet member by a connecting mechanism which includes an elongate, flexible member capable of extending from the second weight inside the water tank to a connecting point outside the water tank.  A holding mechanism releasably holds the connecting mechanism, which prevents the toilet member from pivoting from a lowered position to a raised position until the holding mechanism is disengaged.  If the toilet member is in a raised position when the toilet is flushed, the toilet member will move to its lowered position due to downward movement of said second weight.

Title: Waveguide grating router having relatively small dimensions
Inventor: ZIRNGIBL MARTIN
IPC: G02B6/34
Filed: 1997-10-08
Abstract: A compact waveguide grating router is constructed by forming at least first and second free space regions, first and second sets of optical ports, and a grating array, onto a substrate.. The grating array is coupled to the first free space region and the second free space region. A first plane defining a first reflective surface is introduced into the first free space region, and a second plane defining a second reflective surface is introduced into the second free space region. The first plane is oriented such that incident optical signals from the first set of optical ports are reflected to the grating array, and the second plane is oriented such that incident optical signals from the grating array are reflected to the second set of optical ports. The first and second planes are provided, for example, by cleaving, cutting, etching, sawing, or any other suitable technique. The first and second planes enable the input and output ports to be folded back into previously unoccupied space. The aforementioned techniques enable the size of any conventional waveguide grating router to be substantially reduced.

Abstract: Dans une cellule d'électrodéposition, on usine une anode existante, radiale et constituée de plomb, d'utilisation classique en électrodéposition, de façon à ce qu'elle ait un rayon spécifique. On obtient ainsi une surface usinée courbe qui permet à l'anode en plomb de servir de structure de support. On forme une anode étalon fine en feuille, aux dimensions stables, à partir d'une multitude d'anodes en bandes disposées côte à côte, chaque anode en bande étant formée généralement avec un rayon supérieur au rayon de la structure de support. On peut préalablement incurver les bandes de l'anode en feuille pour constituer une série de membrures. On plie les anodes en bande (12) pour les mettre en place sur la surface de la structure de support (5) en plomb. On peut fixer ces bandes à la structure de support au moyen d'une série d'organes de fixation attachés au dos de chaque anode en bande, lesdits organes pouvant faire saillie vers l'intérieur ou au travers de trous ménagés dans la structure de support en plomb. On peut assurer la connexion électrique, par exemple par l'intermédiaire des organes de fixation, la structure de support en plomb jouant le rôle d'élément distributeur de courant. La structure de support en plomb, qui peut être légèrement soluble dans l'électrolyte de la cellule, est protégée par l'anode en feuille. Il est en outre possible de retirer ladite anode en feuille, par exemple pour la remise à neuf du revêtement d'une anode active.
