Patent number: 9423211Abstract: 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.Type: GrantFiled: November 3, 2014Date of Patent: August 23, 2016Assignee: TRUCKVAULT, Inc.Inventor: Francis Ho

Patent number: 6737853Abstract: 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.Type: GrantFiled: October 18, 2001Date of Patent: May 18, 2004Assignee: NPTest, LLCInventors: Kenneth R.

Patent number: 6588673Abstract: 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.Type: GrantFiled: February 8, 2000Date of Patent: July 8, 2003Assignee: Mist Inc.Inventors: Victor Chan, Francis Ho

Patent number: 6086774Abstract: A method of making released structures by using at least two directional etching steps. Cantilevers, bridges and many other structures can be made with the present invention. In a preferred embodiment, two directional etching steps are performed at opposing angles nonnormal to the substrate surface such that the substrate is undercut and a structure is released. Alternatively, more than two directional etching steps may be performed at various angles. For example, the substrate may be rotated continuously during the directional etching process. A cantilever formed by the method of the present invention necessarily has a substantially triangular cross section. Directional etching processes that can be used include focused ion beam etching and ECR plasma etching. Some directional etching processes may require the use of a patterned etch resist layer. Other etching processes such as focused ion beam etching may use scanning techniques to select which regions are etched.Type: GrantFiled: December 18, 1997Date of Patent: July 11, 2000Assignees: The Board of Trustees of the Stanford Leland Junior University, Japan Science and Technology CorporationInventors: Francis Ho, Yoshihisa Yamamoto

Patent number: 5847569Abstract: An all-electrical high frequency contact sampling probe provides sub-micron spatial resolution and picosecond or sub-picosecond temporal resolution. In a preferred embodiment, the probe is a monolithic integration of a sampling circuit with a cantilever and probe tip, where the distance between the circuit and the tip is less than a wavelength of interest in an RF signal ?V.sub.RF !. The sampling circuit ?44! uses Schottky diodes ?SD! for sampling the RF signal ?V.sub.RF ! from a device under test at a rate determined by local oscillator signals ?50, 52!. An IF signal ?V.sub.IF ! produced by the sampling probe is an equivalent time representation of the RF signal. Applications include testing signals at interior nodes of high speed integrated circuits.Type: GrantFiled: August 8, 1996Date of Patent: December 8, 1998Assignee: The Board of Trustees of the Leland Stanford Junior UniversityInventors: Francis Ho, David M.

Patent number: 5488305Abstract: 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.Type: GrantFiled: September 28, 1994Date of Patent: January 30, 1996Assignee: The Board of Trustees of the Leland Stanford Junior UniversityInventors: David M.
