  • Patent number: 8169356
    Abstract: A motion sensing method and apparatus includes a housing enclosing a microwave motion sensor including an antenna, and a security system. The antenna may be a patch antenna which includes microwave radiating elements for transmitting and receiving a microwave signal for sensing motion. A reflector is attached to the housing and positioned above the antenna for downward shaping of the microwave signal. The microwave radiating elements together with the reflector provide a radiation pattern where a main beam is transmitted in a direction orthogonal to a surface of the antenna and a sided lobe is transmitted downward in amplitude below the microwave motion sensor. An alarm circuit indicates when the microwave sensor detects motion in armed mode, and a masking circuit indicates when the microwave sensor detects motion in a mask zone when the security system is unarmed. A second sensor may be positioned beneath the microwave motion sensor.

  • Publication number: 20120071214
    Abstract: A passively re-radiating cell phone sleeve assembly capable of conforming to and nesting with a cell phone provides a partial enclosure capable of fitting over at least a portion of the cell phone. A multi-layer radio frequency (RF) coupling probe is fully embedded within the enclosure in a position that is in close proximity to an internal antenna of the cell phone when the enclosure is nested with the cell phone. A coupling probe is inductively coupled to the internal antenna for sharing RF signals and is desensitized from de-tuning the internal antenna of the cell phone. An external antenna is mounted on the enclosure; and a transmission line embedded within the enclosure joins the coupling probe and the external antenna for RF signal transfer. RF transmission signals of the cell phone are radiated from both the internal and the external antennae simultaneously and without mutual interference.

  • Patent number: 8074638
    Abstract: Embodiments of the present invention relate to concentrating solar radiation using an assembly of at least one clear and one reflective film that inflates into a shape reflecting parallel rays of light to a concentrated focus in the interior or immediate proximity of the assembly. Embodiments of the present invention can be assembled in a substantially flat stack with bonds or welds between the films, compatible with conventional high-throughput film manufacturing processes. Embodiments in accordance with the present invention may employ external circumferential rings or a “harness” assembly to support and point the balloon against wind forces and the like without severe stress localization. Embodiments in accordance with the present invention may also employ film attachments to facilitate feedthroughs, reduce stress concentrations, and modify the inflated shape. Embodiments in accordance with the present invention may also employ film modifiers, including laminated films, adhesives, printing, etc.

    Abstract: A magnetic-guiding laminate is used to improve wireless communication between a transmitter and a receptor disposed on a substrate, regardless of the substrate materials. The laminate can comprise one or more layers of magnetic or non-magnetic material with different magnetic property. For example, the laminate can comprise a paramagnetic layer disposed on a diamagnetic layer, where the paramagnetic layer attracts the magnetic field toward the RFID antenna, and the diamagnetic layer prevents the magnetic field from dispersing in the substrate. Alternatively, the laminate can comprise multiple paramagnetic layers, wherein at least two layers have different magnetic properties, such as different permeability values.
