  • Publication number: 20240415399
    Abstract: The systems, devices, and methods presented herein use a heart pump to obtain measurements of cardiovascular function. The heart pumps described herein can operate in parallel with and unload the heart. The system can quantify the functioning of the native heart by measuring certain parameters/signals such as pressure or motor current, then calculate and display one or more metrics of cardiovascular function. These metrics, such as left ventricular end diastolic pressure (LVEDP), left ventricular pressure, and contractility, provide valuable information to a user regarding a patient's state of heart function and recovery.

  • Patent number: 10657568
    Abstract: An interactive user interface is disclosed that enables users to efficiently access and/or submit component-specific reviews of components of a product. The user interface displays an image of the product, and displays region identifiers that identify image regions corresponding to product components that are separately reviewable. When a user selects a particular region, the user interface may display component-specific reviews of the corresponding component, and/or may display an option to submit a component-specific review of the component. The user interface may be included in an interactive catalog page, such as a web page.

  • Patent number: 7554805
    Abstract: The present invention discloses a heat-dissipation structure for electronic devices, which comprises: a housing having an accommodation space accommodating at least one heat-generating element; a heat conductor arranged in the accommodation space and contacting the heat-generating element; and an electric fan arranged outside the housing. The housing has an opening corresponding to the heat conductor, and the heat conductor extends through the opening and projects from the housing. The electric fan drives an air current to flow through the part of the heat conductor extending through the opening to promote heat-dissipation efficiency.

  • Publication number: 20080316698
    Abstract: A damping structure for electronic devices has a holding rack mounted onto a chassis to hold an electronic device. The holding rack has two ends extended towards the chassis to form respectively a step portion and a first coupling section extended from the step portion. The holding rack has two other ends extended sideward to form second coupling sections to form a holding space for the electronic device. There are damping assemblies interposed between the holding rack and the chassis, and between the holding rack and the electronic device. The damping assemblies are independent and can provide elastic damping forces.

  • Publication number: 20060197673
    Abstract: A light modulation system as described herein can be incorporated into a personal or portable electronic apparatus such as a cellular telephone, a digital music player, or the like. The light modulation system controls the activation of light elements, such as light emitting diodes, of the host electronic apparatus in response to one or more analog audio signals available at the host electronic apparatus. The analog audio signals may be obtained from any suitable analog audio path or source in the host electronic apparatus. The light modulation system is compact, inexpensive to implement, and need not rely on digital signal processors for operation.
