Abstract:
A method and an apparatus for executing codes embedded inside a device to verify a code image loaded in a memory of the device are described. A code image may be executed after being verified as a trusted code image. The embedded codes may be stored in a secure ROM (read only memory) chip of the device. In one embodiment, the verification of the code image is based on a key stored within the secure ROM chip. The key may be unique to each device. Access to the key may be controlled by the associated secure ROM chip. The device may complete establishing an operating environment subsequent to executing the verified code image.
Abstract:
A method and an apparatus for establishing an operating environment by certifying a code image received from a host over a communication link are described. The code image may be digitally signed through a central authority server. Certification of the code image may be determined by a fingerprint embedded within a secure storage area such as a ROM (read only memory) of the portable device based on a public key certification process. A certified code image may be assigned a hash signature to be stored in a storage of the portable device. An operating environment of the portable device may be established after executing the certified code.
Abstract:
A catheter with a balloon anchor may be sized to fit through an inner needle and introduced into the patient through the needle. The inner needle may comprise an atraumatic needle with a side port and/or a blunt tip. The catheter may include a radiopaque coil disposed over the distal portion of the catheter body to assist with catheter placement when viewed with fluoroscopy and/or x-ray. The distal portion of the catheter can be very flexible. A balloon inflation tube may terminate proximal to a proximal end of the expandable balloon anchor such that the distal portion of catheter can be flexible. This termination of the inflation tube may also position the inflation tube away from the annulus and nerve roots, so as to avoid irritation of the annulus and rubbing of the nerve roots that may potentially obscure FAD test results.
Abstract:
Methods and systems for managing power consumption in data processing systems are described. In one embodiment, a data processing system includes a general purpose processing unit, a graphics processing unit (GPU), at least one peripheral interface controller, at least one bus coupled to the general purpose processing unit, and a power controller coupled to at least the general purpose processing unit and the GPU. The power controller is configured to turn power off for the general purpose processing unit in response to a first state of an instruction queue of the general purpose processing unit and is configured to turn power off for the GPU in response to a second state of an instruction queue of the GPU. The first state and the second state represent an instruction queue having either no instructions or instructions for only future events or actions.
Abstract:
A method is described for call treatment based on user association with one or more user groups. The method includes receiving a phone call from a call source that is directed to a call recipient, identifying a user group associated with the call recipient, and determining a number of received indications assigned to the user group. The received indications are assigned to the user group by users associated with the user group, and the received indications reflect a desire by the users for a special treatment of future calls from the call source. The method also includes distinguishing treatment of the phone call from the call source based on the number of received indications.

Abstract:
The invention is based on the discovery of the epitope in the Stx2 protein for the 11 E1O antibody. The invention features compositions containing non-full length Stx2 polypeptides that include the 11 E1O monoclonal antibody epitope. The invention also features methods of producing anti-Stx2 antibodies specific for the 11 E1O epitope of the Stx2 protein. Additionally, the invention features methods for treating a subject having, or at risk of developing, a Shiga toxin associated disease (e.g., hemolytic uremia syndrome and diseases associated with E. coli and S. dysenteriae infection) with a polypeptide that includes the 11 E1O epitope or with an anti-Stx2 antibody developed using the methods of the invention. Furthermore, the invention features the detection of Stx2 in a sample using the antibodies developed using the methods of the invention.
Abstract:
A device, system, or method to position variable guide vanes disproportionately is provided. An adjusting device for guide vanes of an axial-flow machine, includes a plurality of rotatably mounted rings of variable guide vanes, a plurality of levers which are arranged on the outer sides of a guide vane carrier for rotating the variable guide vanes, a plurality of adjusting rings, each of the adjustment rings is arranged coaxially to the guide vane carrier and to which a first end of one of the levers is connected, and an adjusting drive with which the adjusting rings may be moved in the peripheral direction. At least one of the levers is set up to perform at least partly a disproportionate longitudinal movement of the first end of the at least one lever.
Abstract:
An apparatus and control system for establishing and maintaining a user selected magnitude and direction of pneumatic resistance provided by exercise equipment includes at least one electrically controlled regulator for admitting air to and releasing air from the pneumatic system, transducer for measuring air pressure within the system and providing a corresponding signal, potentiometer for setting and monitoring system pressure in response to signal input from the transducer, air accumulator tank, and pneumatic piston cylinder assembly. The apparatus may also include at least one user controlled electrically switchable four way valve for providing bi-directional resistance. The apparatus is adaptable for providing unilateral or bilateral exercise movements, with or without bi-directional resistance, and can be used to provide range of motion exercise without resistance.
Abstract:
A search query that includes a first spelling of a term is received. A second spelling of the term is generated. A first set of items that are associated with the first spelling of the term is accessed, and a second set of items that are associated with the second spelling of the term is accessed. A comparison is performed between the first set to the second set. A determination is made as to how to respond to the search query based, at least in part, on the comparison. The response may include a suggested search query that includes the second spelling of the term. The second spelling may be a suggested spelling correction or an alternative spelling. The response may include search results that are relevant to a search query that includes the first spelling of the term, the second spelling, or both the first and second spelling.
