| 20120081141 | On-Chip Delay Measurement Through a Transistor Array - Methods and apparatus are provided for measuring a delay through one or more transistors in an array of transistors. The delay through one or more transistors in an array of transistors is measured by selecting one of the transistors in the array; and applying a clock signal to the selected transistor, wherein an output of the selected transistor is applied to a first input of a logic gate having at least two inputs and wherein a second clock signal based on the clock signal is applied to a second input of the logic gate, and wherein an output of the logic gate indicates a difference in arrival times of the signals at the two inputs. In one variation, a clock signal is applied to the selected transistor and a variable delay circuit; and an output of the selected transistor is applied to a data input of a latch having a clock input and a data input while an output of the variable delay circuit is applied to a clock input of the latch. The delay applied by the variable delay circuit to the clock signal is adjusted until a predefined transition is detected in an output of the latch.

| 20120081143 | DELAY CHAIN BURN-IN FOR INCREASED REPEATABILITY OF PHYSICALLY UNCLONABLE FUNCTIONS - A circuit and method increases the repeatability of physically undetectable functions (PUFs) by enhancing the variation of signal delay through two delay chains during chip burn-in. A burn-in circuit holds the inputs of the two delay chains at opposite random values during the burn-in process. All the PFETs in the delay chains with a low value at the input will be burned in with a higher turn on voltage. Since the PFETs affected in the two delay chains are driven by opposite transitions at burn-in, alternating sets of delay components in the two delay chains are affected by the burn-in cycle. Under normal operation, both of the delay chains see the same input so only one chain has an increase in delay to achieve a statistically reliable difference in the two delay paths thereby increasing the overall repeatability of the PUF circuit. | 2012-04-05 |

The system includes a central application that has a dynamic roadmap definition module adapted to at least allow a user to arbitrarily define features in a geographical information systems database and import overhead imaging data corresponding to a geographical area in which said features are defined. The central application includes a remote position and attitude reception module adapted to at least receive data concerning the position of at least one remote vehicle, a transceiver module adapted for exchanging data with at least one remote vehicle; and a logging and tracking module adapted for at least logging said position of at least one remote vehicle over time. The system also has a remote application; and a communications link adapted for exchanging data between the central application and the remote application. | 2012-04-05 |
| 20120081238 | Contextual information encoded in a formed expression - Embodiments include a method, a manual device, a handheld manual device, a handheld writing device, a system, and an apparatus. An embodiment provides a manual device operable in a context. The manual device includes a writing element operable to form a mark on a surface in response to a movement of the writing element with respect to the surface. The manual device also includes a controller operable to encode information corresponding to the context of the manual device by regulating the formation of the mark. | 2012-04-05 |
| 20120081239 | UPDATING A KEYBOARD CONFIGURATION - Embodiments disclosed herein relate to updating a keyboard configuration. A keyboard configuration may be determined. The keys may be assigned a meaning based on the determined configuration where groups of adjacent keys are assigned the same meaning. An image for each of the keys may be determined based on the assigned meaning, and the determined image may be displayed on the keyboard keys. | 2012-04-05 |
| 20120081240 | PORTABLE TERMINAL HAVING KEYPAD - A portable terminal has a keypad. The portable terminal includes the keypad including a plurality of key buttons in a predetermined pattern and forming an antenna pattern by using devices connected to both ends of predetermined key buttons among the plurality of key buttons, a Radio Frequency (RF) communicator connected to signal lines of the predetermined key buttons of the keypad, a digital circuit for recognizing a signal input to the keypad, and a controller for controlling the keypad to be selectively switched to one of the digital circuit and the RF communicator according to a signal generated in a resonance frequency region of a particular service band. | 2012-04-05 |
