Abstract: This invention relates to an arrangement for selecting a local dealer out of a large group of dealers for completion of an 800 number. The caller is first connected to a toll switching system. That system sends a query to a first database using the 800 number and the caller's Numbering Plan Area (NPA) code. The first database responds with a routing number which is used to route a second query to one of a plurality of second databases. The second query uses the routing number and the caller's NPA plus office code to access the second database and to obtain the telephone number of a local dealer. The telephone numb is returned to the toll system for completing the call. Advantageously, a caller can use a number advertised on national television to access a local dealer.

Title: Ophthalmic measurement apparatus
Inventor: AKIYAMA KOUICHI
IPC: A61B3/12
Filed: 1992-03-05
Abstract: An ophthalmic measurement apparatus comprises a laser beam projection section for projecting into an eye a linearly polarized laser light beam emitted by a laser source(1), and a light receiving section provided with a photosensor (27) for detecting laser light scattering from within the eye. An angle of the optical axes formed by both the sections with respect to the eye is set to be substantially ninety degrees. The polarization direction of the laser beam from the laser beam projection section is made variable in such a way that, during alignment (Fig 9a), the polarization direction is set substantially perpendicular to a plane that includes the optical axes of both the sections, and during measurement (Fig. 9b) it is set in a direction that is substantially in the plane. This arrangement makes it possible to cut noise components caused by light scattered by flares which are much smaller than the wavelength of the light.

Abstract: An economical process is used for producing high-quality security tags, if, first of all, a hard-magnetic metal strip 5 is adhesively bonded to a non-metallic tape 3 and then a carrier film 6 is adhesively bonded onto the metal strip 5, which carrier film has a thickness and elasticity such that a punching die 7 causes, at the point of its action on the metal strip 5, an elastic deformation of the metal strip 5 and of the carrier film 6 which is sufficient to sever the metal strip 5. For this purpose, a rapidly and precisely operating rotating punching die 7 may be used, which punches parts 8 out of the non-metallic tape 3 and the metal strip 5, which parts 8 are detached from the carrier film 6. On the remaining parts of the hard-magnetic metal strip 5, a soft-magnetic metal tape 12 is applied. Subsequently thereto, tag paper 13 is adhesively bonded to one side of the layer material produced in the manner described above and a carrier tape 15 is adhesively bonded to the other side thereof, so that an intermediate product is produced from which tags can be punched. <IMAGE>

Abstract: A trace circuit comprises a latch for latching a base pointer of local variables and a latch for latching a program execution address. At the time of a data access, the content of the base pointer latch and the content of the program execution address latch are written to the trace memory together with the accessed address, data and status. A variable offset of the local variable is calculated from the address and the value of the base pointer recorded in the trace memory. The debug information table of a program being debugged is searched by this variable offset and the program execution address recorded in the trace memory, so that the local variable is made to correspond to the data access content stored in the trace memory. Thus, the efficiency of the debugging is improved by using a tracer in the course of debugging a program described in high level language such as C language.
