20080228035ENDOSCOPE AND HYDROPHILIC CAP - An endoscope includes: an insertion portion including a distal end portion, to be inserted into a subject; an observation optical system disposed in the insertion portion; an optical member configuring a part of an outer surface of the distal end portion, through which a photographing light to be incident into the observation optical system transmits; a first hydrophilic portion that is film-formed at least on a surface of the optical member; a second hydrophilic portion that is film-formed on a first surface of the distal end portion in which the optical member is disposed; and a third hydrophilic portion that is film-formed on a second surface separate from the first surface of the distal end portion.09-18-2008
20090181964Propane-1,3-Dione Derivative or Salt Thereof - It is intended to provide a compound useful as a GnRH receptor antagonist. The inventors further investigated propane-1,3-dione derivatives. As a result, they confirmed that a compound having a benzene ring or a thiophene ring substituted with a group represented by —SO07-16-2009
20100277581MICROSCOPE - A microscope, which moves an objective lens along an observation optical axis with respect to a specimen, includes an imaging unit and a supporting unit. The imaging unit has an imaging lens, which is arranged on the observation optical axis and forms an observation image of the specimen, and an imaging element, which is arranged on the observation optical axis and takes the observation image, and is optically connected to the objective lens by a parallel light flux. The supporting unit fixedly supports the imaging unit, and movably supports the objective lens.11-04-2010

20100169624Adaptive Fetch Advance Control for a Low Power Processor - A digital signal processor (DSP) includes an instruction buffer queue (IBQ) with multiple lines, as well as a modifiable fetch advance parameter to specify a fetch advance setting for the IBQ. The DSP also has a control flow module. In response to execution of a program in the DSP, the control flow module may automatically determine whether a branch has been predicted for the program, or for a portion of the program. The control flow module may automatically reduce the fetch advance parameter in response to determining that a branch has been predicted for the program. Also, the control flow module may automatically increase the fetch advance setting in response to determining that no branch has been predicted for a portion of the program. Other embodiments are described and claimed.07-01-2010

20090083862PROVIDING SECURE INPUT TO A SYSTEM WITH A HIGH-ASSURANCE EXECUTION ENVIROMENT - Methods for maintaining the security of a secured execution environment on a system comprising said secured execution environment and a second execution environment are disclosed. A maintained current state for the secured execution environment is selected from among a group of possible states including a standard input mode state and a nexus input mode state. A flow of user input is directed according to the current state through a secure kernel of both the second environment and the secured execution environment.03-26-2009
20090207055METHOD FOR PROCESSING DATA QUANTIFYING FORCE APPLIED TO ONE OR MORE KEYS OF A COMPUTER KEYBOARD - A computer receives data from a keyboard having one or more keys which cause generation of keyboard data that quantitatively describe the relative force applied to those keys. The keyboard data are transmitted in an HID report containing identifiers for one or more keys that have been pressed and force data for each key. The force data may be a multi-bit value quantifying the key force, or a null indicator signaling that the key is not force-sensing. Keyboard data messages are then prepared which identify keys pressed, contain force data, and may indicate whether the force data updates previous force data. Force updates are only provided to application programs registering for key force data. In other aspects of the invention, key repeat messages are automatically generated for a key held pressed by a user. The key repeat messages are generated at a rate controlled by the amount of force applied to the key.08-20-2009
20100031320USER INDICATOR SIGNIFYING A SECURE MODE - Computer-readable media, computerized methods, and computer systems for alerting a user that an operating system has entered a secure mode is provided. Initially, inputs are received at an operating system residing in a default mode. Typically, the default mode allows applications running on the operating system to access the inputs. If the inputs are identified as a call to perform a protected operation, the operating system is transitioned from the default mode to the secure mode. Typically, the secure mode restricts the applications from intercepting the inputs. The transition to the secure mode is automatically communicated to the user via an indicator device. Generally, automatic communication includes providing a message from the operating system to the indicator device over a secure pathway that triggers the indicator device to generate a user-perceivable output. Accordingly, the operating system exerts exclusive control over the operation of the indicator device.02-04-2010
