Title: Communication system having a packet structure field.
Inventor: DELUCA JOAN SABIN
IPC: H04B7/26
Filed: 1989-05-04
Abstract: A communication system develops an information packet having a packet structure field and at least one message. The message has an address and information associated with the address. A central station accumulates and incorporates the at least one message into the information packet. The central station determines the occurrence of the at least one address and generates identifying data indicating where the address occurs within the information packet. The identifying data is incorporated into the packet structure field and the information packet is transmitted. The information packet is received by at least one selective call receiver capable of operating in a high power mode in order to receive the information packet and a low power mode when receiving is not being performed. The selective call receiver extracts the packet structure field and interprets the identifying data. The identifying data is used to operate the selective call receiver in the high power mode only during the occurrence of the at least one address. The selective call receiver operates in the low power mode for the remainder of the information packet unless the information associated with the address is intended to be received by the selective call receiver.

Abstract: Procedure for optical quality inspection of large-faced panes of a transparent material like glass, in particular of motor vehicle windscreens, with the aid of a moiré image evaluation, in which an illuminated surface-area grid is imaged via a lens on a reference grid and the moiré image is generated as a superimposition of the image of the surface-area grid and the reference grid. The reference grid is arranged on a light wall uniformly illuminated from behind, which corresponds at least to the size of the motor vehicle pane to be inspected. The pane to be inspected is arranged between the surface-area grid and lens. The surface-area grid is imaged on a reference grid whose surface area corresponds to a fraction of the surface area of the motor vehicle pane to be inspected. The superimposition is recorded by a video camera and evaluated using a phase shift procedure. The brightness distribution recorded by the video camera is used as a measure of the refractive power.

Abstract: A device for forming an inserting hole comprising at least two tubes having different outer diameters, and at least one of a guide wire and a sticking needle. A largest diameter tube (T) has at its thick-walled end (10) at least one longitudinal and approximately linear tearing line (8). The largest diameter tube (T), after being inserted into the body, can be torn using the tearing line (8) and fixed to the skin of a patient by sewing a folded portion of the tube (T) on the skin. The tube (T) is not moved by the breathing or pressure since it is fixed to the skin. When the tearing line (8) is formed by an ultrasonic cutter, width (W) of the tearing line (8) can be made narrow thereby preventing adhesion of bacteria to a cut portion (13) and unexpected opening of the tearing line (8) in the body.

IPC: G02B6/13
Filed: 1990-09-10
Abstract: In semiconductor layer structures in which at least two semiconductor layers having different thicknesses and consisting of different semiconductor materials are present, mesas can be formed by means of wet-chemical etchants and with the use of a mask. A disadvantage of the etchants available is that it is difficult to form mesas having substantially flat side walls with a small under-­etching and with an accurately determined width, especially of the thinner layer. This is an unfavourable starting situation for the manufacture of, for example, radiation guides and semiconductor diode lasers, in which such mesas are formed. 
     In the method according to the invention, the upper and thicker of the two semiconductor layers is etched by means of a selective and preferential etchant, substantially no underetching occurring with respect to the mask. Subsequently, the lower and thinner semiconductor layer and a part of the upper semiconductor layer are converted by a substantially non-selective anodic oxidation into semiconductor material oxides, which are removed by means of an etchant which is non-selective with respect to the oxides formed, but is selective with respect to the semiconductor materials. As a result, mesas are obtained having a substantially flat side wall, the lateral dimension of these mesas being accurately determined by the size of the mask. Thus, particularly favourable results are obtained, especially in the InP/InGaAsP material system. The method according to the invention can be used very advantageously when the thinner layer forms part of a so-­called multilayer quantum well structure. In a particular embodiment, a further mask is provided above the mask in such a manner that it projects beyond the mask, the side   walls of the mesa being made substantially straight, as a result of which the method is particularly suitable for providing by means of OMVPE further semiconductor layers on either side of the mesa, which results in a substantially flat buried structure.
