20100109875 | Noninvasive Motion and Respiration Monitoring System - A non-invasive motion and respiration monitor receives impulses from a subject's movement, heartbeat, and respiration. The raw signal is biased and digitized, and a signal processor applies a Fast Fourier Transform to the signal. The transformed signal is filtered to isolate the component representing heart rate from the component representing respiration. An Inverse Fast Fourier Transform is then applied to the component signals, which are sent to a processor. The processor is programmed to detect irregularities in the respiration and heart rate. If severe irregularities or complete cessation is detected in either signal, a mechanical stimulator is actuated to try to stimulate the subject, and an alarm is sounded to alert a caregiver such as a parent or nurse. | 05-06-2010 |
20100160994 | CARDIOVASCULAR POWER SOURCE FOR AUTOMATIC IMPLANTABLE CARDIOVERTER DEFIBRILLATORS - Aspects according to the present invention provide a method and implant suitable for implantation inside a human body that includes a power consuming means responsive to a physiological requirement of the human body, a power source and a power storage device. The power source comprises a sheathed piezoelectric assembly that is configured to generate an electrical current when flexed by the tissue of the body and communicate the generated current to the power storage device, which is electrically coupled to the power source and to the power consuming means. | 06-24-2010 |

20140230574 | IMPACT-RESISTANT SURFACE-MOUNTED ROOF SENSORS - Various systems and techniques may be used to enhance the sensing loads on a roof surface. In some implementations, an impact-resistant surface-mounted roof sensor system may include a sensor, a protective cover, and a load transfer mechanism. The sensor may be adapted to sense a load incident thereon, and the protective cover may be configured to span at least the width of the sensor and adapted to withstand impacts from dense media and an direct incident load. The load transfer mechanism may be adapted to mechanically transfer a load applied on the protective cover to the sensor. | 08-21-2014 |
20150017466 | SELF-ALIGNED TUNABLE METAMATERIALS - A self-aligned tunable metamaterial is formed as a wire mesh. Self-aligned channel grids are formed in layers in a silicon substrate using deep trench formation and a high-temperature anneal. Vertical wells at the channels may also be etched. This may result in a three-dimensional mesh grid of metal and other material. In another embodiment, metallic beads are deposited at each intersection of the mesh grid, the grid is encased in a rigid medium, and the mesh grid is removed to form an artificial nanocrystal. | 01-15-2015 |
