20090162071 | Auto-Tracking System for Mobile Free-Space Optical (FSO) Communications - Free-space optics (FSO) is an unlicensed line-of-sight technology that uses modulated optical lasers to transmit information through the atmosphere. By using invisible beams of light, FSO can transmit and receive voice, video, and data information. To date, the primary concentration of FSO research and development has been toward the accurate alignment between two transceivers. The invention (FSO system) provides viable optical beam steering and capturing mechanism to allow fast tracking and accurate pointing between two transceivers of free-space optic (FSO) link that required continuous alignment. This extra ordinary auto-tracking system can reduce the time needed to lock a laser beam between an aircraft and a stationery base station to exchange information in addition to its high accuracy. This invention also provides wider receiving angle compared with the conventional FSO system. | 06-25-2009 |
20090240168 | Remote Cervical Dilation Monitoring System and Method - A cervical dilation monitor for measuring the dilation of a cervix and for providing cervical data to an external wireless unit. The cervical dilation monitor comprises a housing, a sensor, a controller, and a power source. The housing is constructed of a biocompatible material and is adapted to be connected to portions of a cervical lip. The sensor is supported by the housing so as to generate signals related to cervical dilation. The controller includes a transceiver and a processor. The transceiver receives and transmits the cervical dilation data to the external wireless unit. The processor receives the signals generated by the sensor related to the cervical dilation and enables the transceiver to wirelessly transmit the cervical dilation data. The power source provides power to the controller. | 09-24-2009 |
20110060251 | REMOTE CERVICAL DILATION MONITORING SYSTEM AND METHOD - A method of monitoring the cervical dilation of a pregnant female, comprising the steps of receiving cervical dilation data generated by a cervical dilation monitor having a sensor including a coil measuring an inductance with the coil attached to a housing such that expansion of the housing changes the inductance of the coil. Then, the cervical dilation is correlated to the immediacy of delivery to create immediacy data and/or one or more instructions indicative of the immediacy of delivery. The immediacy data and/or one or more instructions is transmitted so as to inform the pregnant female of the immediacy of delivery. | 03-10-2011 |
20110063577 | 3D Light Surface Display - A light surface display for providing a three-dimensional image including a plurality of particles suspended within a volumetric display. A first projection system projects sequential slices of electromagnetic energy of one or more wavelengths along the length and width of the volumetric display energizing particles to form a two-dimensional image. A second projection system projects translational slices of electromagnetic energy of one or more wavelengths that intersect with the energized particles across the depth of the volumetric display. A control system synchronizes the projection of the image source and the activation source such that the two-dimensional image and the translational slices energize the particles for a pre-determined length of time so that the particles illuminate to form an illuminated three-dimensional image. | 03-17-2011 |
20120044460 | 3D Volumetric Display - A light surface display for providing a three-dimensional image including a plurality of particles dispersed within a volumetric display. A first projection system projects sequential slices of electromagnetic energy of one or more infrared wavelengths along the length and width of the volumetric display energizing particles to form a two-dimensional image. A second projection system projects translational slices of electromagnetic energy of one or more infra-red wavelengths that intersect with the energized particles across the depth of the volumetric display. A control system synchronizes the projection of the image source and the activation source such that the two-dimensional image and the translational slices energize the particles for a pre-determined length of time so that the particles illuminate to form an illuminated three-dimensional image. | 02-23-2012 |

The algorithms includes instructions for capturing an electronic-ink image, instructions for converting the electronic ink image into control instructions for controlling an electromechanical aspect of the imaging display, and, instructions for providing the control instructions to control circuitry of the imaging display. Interfacing projection systems and methods of interfacing electronic-ink images are also described. | 11-01-2012 |
20120274907 | 3D Volumetric Display - A light surface display for providing a three-dimensional image having a volumetric display, a first projection system, and a second projection system. The first projection system projects electromagnetic energy into the volumetric display sequentially along the length and width of the volumetric display in a series of 2D image slices. The second projection system projects electromagnetic energy in a series of slices along the depth of the volumetric display. Particles intersected by the first and second wavelengths form illuminated two-dimensional cross sections at specific locations in the volumetric display. | 11-01-2012 |
