Abstract:
A ceramic heater is provided that includes a thermocouple having a hot or measuring junction in a form of a bead directly bonded to a ceramic substrate by an active brazing material. Alternatively, a metallized layer is provided on the ceramic substrate and the bead of the thermocouple is directly bonded to the metallized layer by an ordinary brazing material. Due to the direct bonding of the bead to a ceramic substrate, the temperature of the bead reflects the temperature of the ceramic heater almost instantaneously so that the thermocouple can more accurately measure the temperature of the ceramic heater.
Abstract:
A pipeline tester is disclosed that is capable of testing systems-on-a-chip (SOCs) or Devices Under Test (DUTs) in pipeline fashion. The tester provides faster, more economical testing of such SOCs and DUTs, which are loaded sequentially into the tester. A plurality of underlying test stations are disposed in the tester. Above the test stations are disposed corresponding test fixtures which are configured to receive moveable test beds therein. The test beds are mechanically and electrically connected to the underlying test stations. Loaded within each test bed is an SOC or DUT. One or more electrical or electronic tests are performed on each SOC or DUT while the SOC or DUT is loaded in a test bed positioned above a test station. Once the test has been completed, the test bed is moved to another test station, where another electrical or electronic test is performed. Electrical or electronic tests may be performed in parallel on different DUTs or SOCs loaded into different test beds.

Abstract:
Methods and systems for enhancing the security of data during input and output on a client computer system are provided to prevent attempts by unauthorized code to access, intercept, and/or modify data. Example embodiments provide a plurality of obfuscation techniques and security enhanced drivers that use these obfuscation techniques to prohibit unauthorized viewing/receiving of valid data. When the drivers are used together with the various obfuscation techniques, the security enhanced drivers provide mechanisms for “scheduling” the content of the storage areas used to store the data so that valid data is not available to unauthorized recipients. When unauthorized recipients attempt to access the “data,” they perceive or receive obfuscated data. The obfuscation techniques described include “copy-in,” “replace and restore,” and “in-place replacement” de-obfuscation/re-obfuscation techniques. In one embodiment, a security enhanced display driver, a security enhanced mouse driver, a security enhanced keyboard driver, and a security enhanced audio driver are provided. To complement the security enhancements, the methods and systems also provide for a watchdog mechanism to ensure that the driver is functioning as it should be and various user interface techniques for denoting security on a display device.
Abstract:
Methods, systems, and computer program products for identifying computer source code constructs are disclosed. According to one method, computer source code is converted to a format suitable for an automated inference engine. The automated inference engine receives as inputs the converted source code, a set of elemental design patterns defining patterns to be identified, and a set of rules defining relationships between patterns. The automated inference engine outputs proofs indicative of patterns present in the source code. The proofs may be converted to a source code pattern report.

Abstract:
An intuitive pressurized fluid controller using tilt/push/pull operator includes a swivel joint “(33)” having a through hole “(14)”. A lever “(15)” passes through the hole “(14)” such that it can move axially as well as tiltably. A first array of valves “(18a, 18b, 18c, 18d)” are arranged radially to the lever “(15)” axis so they can be activated either individually or in close pairs as the lever “(15)” is tilted. An actuator “(17)” is attached perpendicularly to and further along the lever “(15)”. A second array of valves “(23a, 23b, 23c, 23d)” are arranged circularly to and parallel to the lever “(15)” and close to the actuator “(17)” so they can be activated when the lever “(15)” is pulled in it's axial direction. A third array of valves “(20a, 20b, 20c, 20d)” are arranged circularly to and in opposite parallel alignment to the lever “(15)” and close to the actuator “(17)” so they can be activated when the lever “(15)” is pushed in it's axial direction. Wherein, when plumbed to a plurality of pressurable positioners “(27a, 27b, 27c, 27d)” supporting a heavy equipment “(24)”, the first radial array of valves “(18a, 18b, 18c, 18d)” can control the equipment “(24)” pitch and roll as the lever “(15)” is tilted, and the second and third arrays of axial valves “(23a, 23b, 23c, 23d and 20a, 20b, 20c, 20d)” can control the equipment “(24)” elevation as the lever “(15)” is pulled and pushed.
Abstract:
A buckle assembly includes a housing enclosing a locking bar for securing a latch. The latch is inserted into a latch cavity of the buckle assembly, pushing the spring-loaded locking bar into the housing until a convex feature of the latch passes a convex feature of the latch cavity, and slides to the side, whereupon the locking bar is extended by a compression spring, thereby locking the latch from release from the buckle assembly. The latch is released from the latch cavity by pulling a release cord or cable or trigger attached to the locking bar to overcome the spring tension and draw the locking bar up, thus allowing the latch to move away from the convex feature of the latch cavity and release from the buckle assembly.

An alignment aid for a firearm includes a first sight having a base portion and a shroud portion. A fiber optic rod has a proximal end, a distal end, and an upper surface that extends between the proximal and distal ends. The fiber optic rod is disposed between the shroud portion and the base portion of the first sight. The shroud portion of the first sight surrounds the upper surface of the fiber optic rod from the proximal end to the distal end of the fiber optic rod and includes a plurality of apertures through the shroud portion of the first sight between the proximal and distal ends of the fiber optic rod.
