    摘要： The apparatus includes a body portion and a door removably connected to the body portion, revealing the interior of the body portion, the door having at least one latching element. An access assembly is attached to the body portion, the access assembly including a latch bar having an opening to receive the latching element. A plurality of actuating buttons are provided for the user. A mechanism responsive to operation of preselected buttons in a preselected sequence releases an actuation mechanism. An operating member accessible to the user and operatively connected to the actuation mechanism moves the released actuation mechanism to move the latching bar so that the latching element is released from the latching bar, allowing the door to be opened.

    摘要： A method of probing voltage comprises: establishing electrical connectivity between a conductor to be probed and a first terminal of a photoconductive switch; during a sampling interval n, applying a laser pulse to the photoconductive switch while applying a voltage to a second terminal of the photoconductive switch corresponding to a voltage sample taken during a prior sampling interval n−1, such that current flow through the photoconductive switch is dependent on any difference between voltage of the conductor and the applied voltage; converting the current flow to a voltage signal; passing the voltage signal during a gating interval and sampling the passed voltage signal to produce a voltage sample for the sampling interval n. A repetitive test pattern applied to the conductor and the sampling interval is synchronized with the repetitive test pattern. Converting the current flow to a voltage signal can comprise applying the current flow to a current-to-voltage converter having a rise time which is less than the gating interval. The voltage signal can be passed only during the gating interval so that the voltage sample is insensitive to any leakage through the photoconductive switch outside of the gating interval. Passing the voltage signal during a gating interval can comprise applying the voltage signal to a first transistor Q1 of a differential pair of transistors Q1, Q2, applying a reference voltage to a second transistor Q2 of the differential pair of transistors, and controlling common emitter current of the differential pair of transistors with an electronic switch so as to pass the voltage signal when the electronic switch is closed. Sampling the voltage signal can comprises applying the voltage signal to an analog-to-digital converter and enabling the analog-to-digital converter to prepare a digital sample of the voltage signal representing voltage on the conductor. Apparatus for carrying out the method is also provided.

    摘要： A potentiometry apparatus for measuring a periodic electrical waveform existing proximate the surface of a sample such as a semiconductor wafer is disclosed herein. The potentiometry apparatus includes a pulse generator for generating a sequence of electrical pulses at a pulse frequency offset from the frequency of the surface waveform by a mixing frequency. A cantilever coupled to the pulse generator serves to carry the electrical pulses to a position proximate the surface of the sample. In a capacitive displacement mode the cantilever is mechanically displaced so as to generate a time-expanded representation of the electrical surface waveform having a repetition frequency equal to the mixing frequency. During displacement mode operation an optical detection circuit may be employed to monitor deflection of the cantilever. In a tunneling current mode the cantilever is again employed to carry the electrical pulses to a position proximate the surface of the sample. In this mode a tunneling current propagating through the cantilever at the mixing frequency provides a time,expanded representation of the electrical surface waveform.

    摘要： An integrated card personalization system is provided using an “in-line” approach for seamless card personalization directly from cardholder data files to avoid duplication of hardware and eliminate the need for an overnight batch process to prepare cardholder data for card personalization. Such integrated card personalization system allows for the personalization of transaction cards such as smart cards on more flexible, low cost, low maintenance and smaller personalization systems so as to save the personalization bureau time and money, particularly on small volume production runs, and eliminate the need to hire and maintain internal software development staff with high attendant cost.
