Title: Data input device with a pressure sensitive input surface
Inventor: FAUST BENEDIKT
IPC: G06F3/033
Filed: 1992-11-27
Abstract: The data input device (11) comprises, above a resistive layer arrangement (2), an arrangement (4) of deformable layers consisting at least partially of dielectric material. This material is elastically deformable so that, when pressure is applied onto the input surface, the distance between the input surface and the resistive layer arrangement (2) is reduced at the pressure point. On the side of the deformable layer arrangement (4) facing away from the resistive layer arrangement (2), there is arranged an electrode which preferably is formed as a conductive layer (1). Thus results in a change of the capacitive properties of the deformable layer arrangement (4) at the pressure point since the thickness of the deformable layer arrangement (4) is reduced on this site. This capacitive measurement is used for detection of the pressing force, while the position of the pressing point within the input surface is detected in two mutually orthogonal directions on the basis of the voltage divider forming in the resistive layer arrangement (2).

Title: Fluorous multiphase systems
Inventor: HORVATH ISTVAN T
IPC: C07D303/32
Filed: 1994-06-27
Abstract: ABSTRACT OF THE DISCLOSURE      Stoichiometric and catalytic  chemical  transformations  may  be carried out in solution using novel fluorous multiphase systems (FMS). The term "fluorous" is defined as a carbon-fluorine bond rich  organic molecule which  is generated  by replacing  hydrogen atoms  bonded  to carbon atoms  with fluorine.   The FMS  consists of  a fluorous  phase containing  a  fluorous  solvent,   typically  a  fluorocarbon  or   a fluorohydrocarbon, either of the foregoing with or without substituent groups, and a reagent or a catalyst containing a sufficient number  of fluorous moieties to render it preferentially soluble in the  fluorous solvent and located at the  interface of the fluorous and  nonfluorous phases.  The nonfluorous  i.e. the  second solvent, may  be any  known organic or nonorganic solvent(s) with limited or no solubility in  the fluorous solvent that is effective for dissolving the reactants and/or separating the  reaction  products. Typically  a  nonfluorous  solvent having a Hildebrand solubility parameter  of at least about 18.0  MPa? is suitable. The  reaction can  occur simultaneously  in the  fluorous phase and at the  interface of the phases.   The FMS reagents and  FMS catalysts in  the  present  invention  contain  sufficient  number  of fluorous moieties  to  render  them preferentially  soluble  into  the fluorous phase and at the  interface without impairing the ability  of the catalyst or reagent to be effective or participate in the reaction and while maintaining the  reaction in a liquid  or fluid phase.   The most  appropriate   fluorous  moieties   are  linear,   branched   and carbocyclic fluorocarbon alkyl  chains with high  carbon numbers  that are effective to  enable the  catalyst or reagent  to remain  fluorous phase compatible.  The fluorous moieties, optionally, may also contain O, S, N,  P, As and  Si, that  assist in rendering  the catalysts  and reagents fluorous phase  compatible.  The FMS  reagents and  catalysts can be prepared by  (1) fluorination (i.e.,  replacement of C-H  bonds with fluorine); (2) fluorofunctionalization, e.g., the attachment  of fluorous moieties  to  the reagents  or  catalysts; or  (3)  by  total synthesis.     The fluorous multiphase systems have utility for facilitating the separation of the FMS catalyst or spent FMS reagent.  The  possibility of separating the catalyst or the spent reagent from the products  has utility in the  design and  synthesis of catalysts  and reagents  with high product  selectivity,  resulting  in  especially  environmentally friendly processes.

Title: Exercise Machine
Inventor: HABING THEODORE G
IPC: A63B21/00
Filed: 1994-07-27
Abstract: A multi-station exercise machine has a movable subframe on which a user sits while performing various exercises. The subframe is pivotally attached to a stationery frame and is supported by a lever arm that is also pivotally attached to the stationery frame. The pivot arms coupling the subframe to the stationery frame bear against a carriage that is movable located on the lever arm. A cable and pulley system couples the lever arm to the various operable members of the apparatus so that a selectable ratio of the weight of the subframe, including the user, is communicated as exercise resistence. The amount of weight that is coupled to the operable members is selected by positioning the carriage along the lever arm. This adjustment also varies the height to which the subframe is lifted by the exercise stroke and hence the effort that must be exerted by the user.

Patent CA-2131509-A1 (CA)
Inventor: DRAGONE CORRADO
IPC: G02F1/313
Filed: 1994-09-06
Abstract: A tunable waveguide grating includes a plurality of N waveguides which define N optically transmissive pathways. A plurality of (N-1) electrodes are arranged in the pathways such that the kth pathway contains (k-1) electrodes, where O < k < N. As a result of this arrangement, an optical signal propagating through the kth pathway will experience a phase shift provided by each of the (k-1) electrodes arranged in that pathway. Consequently, in contrast to prior tunable optical gratings, each electrode may contribute a phase shift to the portions of the signal propagating through several waveguides and hence as the number of waveguides increases no individual electrode is required to produce relatively large phase shifts.
