Date Jun. 13, 1991.Programmable hybrid hearing aid with digital signal processing comprising a main section (1) which can be inserted in the meatus (6). The main section (1) comprises an open connection between the ear opening and an inner portion of the meatus (6), providing an acoustic transmission channel with low-pass characteristic and resonant amplification. The main section further comprises an electroacoustic transmission channel based on digital signal processing and a signal processor (DSP) and with possibility for suppressing a possible acoustic signal feedback through the acoustic transmission channel. A variant of the hearing aid is provided with a microphone (M1) and the feedback signal is suppressed by digital filtering. Another variant of the hearing aid employs two microphones (M1.M2). and the feedback signal may then be suppressed by phasing out before the digital signal processing, while the digital signal processing also comprises cancellation of the feedback signal in case of high gain. A number of response functions are stored in a memory (RAM2) in a control unit and is freely chosen by the user in regard of adaption to hearing function and acoustic environment. All the electronics of the electroacoustic channel in the hearing aid is implemented as a monolithic integrated circuit (3) in CMOS technology.

Granted: 1994-09-13
Abstract: This invention relates to apparatus and a method for use in conjunction with a service wherein a called telephone customer receives a display of the number of a calling telephone customer. In conjunction with this service, customers areoffered a class of service and/or an option to dial a privacy request wherein their telephone number will not be displayed to the called telephone customer. In accordance with this invention, the customers are offered a class of service wherein they will receive calls only from telephone customers willing to have their telephone number displayed. If a call is made from a caller who does not wish to have his number displayed to a called customer who will not accept calls from customers unwilling to identify themselves, the caller is given a special announcement; inresponse to this announcement if the caller keys a special privacy override code then the call is completed with the caller's number displayed. Law enforcement agencies may be provided with a class of service which allows them to obtain a caller's number even when the caller has invoked privacy. Advantageously, such an arrangement protects telephone customers from receiving harassing calls, protects the privacy of those customers who normally do not wish to have their telephone number identified to the called customer, and permits calls to be completed between such customers.

Abstract: A personal computer generates first gray level signals each dot of which is represented by N bits (where N is an integer larger than or equal to 2) representing 2N (the Nth. power of 2) gray levels. The first gray level signal is supplied to a CRT display, each dot of which displays 2N (the Nth. power of 2) gray levels. Now, the CRT is replaced by an LCD, each dot of which displays 2M  (the Mth. power of 2) gray levels. An algorithm converts the first gray level signal of N bits representing 2N gray levels to  second gray level signals representing 2M gray levels. The second gray level signals  are  applied  to the  LCD.  The  invention  solves  a problem raised when an  algorithm is used to generate  an image for LCDs and that image is expanded in a vertical direction.

Granted: 1999-04-06
Abstract: Soap bars contain from 90-50% fatty acid soaps obtained from tallow (non-lauric fats) and 10-50% of fatty acid soaps obtained from coconut (lauric fats).  Known solutions to the problem of harshness include reduction of the level of soap present and replacement of the balance of the composition by so-called co-actives.  A recognised problem engendered by the presence of co-actives is a loss of product structure in the resulting soap bars.  Soap bars which comprise co-actives must therefore be manufactured by a process which increase the cost of the eventual products.  The invention provides soap bars which comprise:   a)   At least 25%wt on total actives of lauric acid soaps, b)   As the balance of the soaps, non-lauric soaps having an iodine value of less than 45, and, c)   At least 5%wt on total actives of one or more synergistic mildness active.            These soap bars have acceptable mildness but can be manufactured with conventional processing equipment.

Abstract: A method of permanently attaching a fastening element, such as a nut or bolt to panels having a range of panel thicknesses, such as the metal panels used by the automotive and appliance industries. The fastening element includes a tubular barrel portion arid preferably an annular bearing face surrounding the barrel portion. The method includes punching a hole in the panel, then plasticly deforming and drawing the panel surrounding the hole into a dome or frusto-comically shaped portion. The panel hole is thus enlarged to receive the fastener element barrel portion from adjacent the apex of the frusto-comically shaped panel portion and the bearing face is then driven against the panel, deforming the panel to a generally planar shape. The panel surrounding the hole is thereby driven against the tubular barrel portion which, in the preferred embodiment, includes radially projecting ribs, forming secure anti-rotation means even in very thin panels.        Finally, the free end of the barrel portion is deformed radially outwardly arid preferably squeezed to form a secure interlock between the fastening element and the panel.
