  • Publication number: 20220004688
    Abstract: Systems and methods are provided for generating a circuit design for an integrated circuit using a circuit design tool. The circuit design tool determines maximum junction temperatures for circuit blocks in the circuit design for the integrated circuit. The circuit design tool determines defects values for the circuit blocks using the maximum junction temperatures for the circuit blocks. The circuit design tool determines a defects value for the circuit design based on the defects values for the circuit blocks. The circuit design tool determines a maximum junction temperature for the circuit design based on a comparison between the defects value for the circuit design and a target defects value for the circuit design. The circuit design tool can dynamically reconfigure configurable logic circuit blocks to improve the power, the performance, and the thermal profile to achieve an optimal junction temperature per circuit block.

  • Publication number: 20200035339
    Abstract: A computer system and method that implements data security with the use of blockchain key encryption for healthcare records that can be accessed across multiple computer systems. The use of one or more blockchain ledgers allows the securing of data with different sets of keys between the computer platforms such that data can ultimately be secured only by the entity that controls the computer system with the healthcare records, with the security system itself only verifying and securing the user's identification data. The system therefore allows the healthcare provider to maintain mandated levels of data security for their stored records, but also allows a user of the system to provide access to other healthcare providers to the records for that user which are resident across multiple computer systems.

  • Patent number: 9308325
    Abstract: Described here are methods, devices, and kits for microjet drug delivery. The devices described here may be modular or non-modular. The modular devices typically include a first module having a drug reservoir and a nozzle in fluid communication with the drug reservoir and a second module having an actuator and a power supply. The power supply provides power to the actuator and when the first and second modules are coupled, the actuator is capable of acting on a dispensing member causing it to dispense a drug in liquid form from the drug reservoir via the nozzle at a velocity sufficient to penetrate skin. Other devices described include a nozzle, a reservoir in fluid communication with the nozzle, a dispensing member, and an actuator. In these devices, the nozzle has at least one feature that enhances nozzle contact with the skin in order to reduce lateral drug leakage about the nozzle.

  • Patent number: 8923686
    Abstract: Methods, systems and computer program products provide a dynamically configurable 3D display utilizing a content receiver. The content receiver generates the 3D content with an offset that enables the images to be viewable in a plurality of 3D regions, where each 3D region and images therein are perceived as having a different degree of depth relative to other images within 3D regions. The user viewing the 3D content may interact with the 3D content through a sensor device communicatively coupled to the content receiver that senses user movements and transmits signals to the content receiver for taking some action in response to the user's movements, including moving the 3D content between various 3D regions. 3D content in a foreground 3D region may be partially transparent to enable viewing of underlying 3D content in a background 3D region. 3D content may include a 3D user interface enabling the user to enter selections.
