Abstract: Disclosed are apparatus and methods for providing outputs; e.g., location estimates, based on signal strength measurements. A computing device can receive a particular signal strength measurement, which can include a wireless-signal-emitter (WSE) identifier and a signal strength value and can be associated with a measurement location. The computing device can determine one or more bins; each bin including statistics for WSEs and associated with a bin location. The statistics can include mean and standard deviation values. The computing device can: determine a particular bin whose bin location is associated with the measurement location for the particular signal strength measurement, determine particular statistics of the particular bin associated with a wireless signal emitter identified by the WSE identifier of the particular signal strength measurement, and update the particular statistics based on the signal strength value. The computing device can provide an estimated location output based on the bins.

Abstract: Disclosed are apparatus and methods for providing outputs; e.g., location estimates, based on trained Gaussian processes. A computing device can determine trained Gaussian processes related to wireless network signal strengths, where a particular trained Gaussian process is associated with one or more hyperparameters. The computing device can designate one or more hyperparameters. The computing device can determine a hyperparameter histogram for values of the designated hyperparameters of the trained Gaussian processes. The computing device can determine a candidate Gaussian process associated with one or more candidate hyperparameter value for the designated hyperparameters. The computing device can determine whether the candidate hyperparameter values are valid based on the hyperparameter histogram. The computing device can, after determining that the candidate hyperparameter values are valid, add the candidate Gaussian process to the trained Gaussian processes.

Abstract: Disclosed are apparatus and methods for providing outputs; e.g., location estimates, based on trained Gaussian processes modeling signals of wireless signal emitters. A computing device can determine first and second trained Gaussian processes. The respective first and second Gaussian processes can be based on first and second hyperparameter values related to first and second wireless signal emitters. The computing device can determine first and second sets of comparison hyperparameter values of the respective first and second hyperparameter values, and then determine whether the first and second sets of comparison hyperparameter values are within one or more threshold values.

Abstract: An indication that a wireless computing device (WCD) is moving toward a physical setting may be received. The physical setting may include a particular topography. There may be at least (i) location-determination information of a first type and (ii) location-determination information of a second type. The location-determination information of the first type may facilitate low-resolution location determinations in the physical setting and the location-determination information of the second type may facilitate high-resolution location determinations in the physical setting. Based on the physical setting and the particular topography, location-determination information may be selected from at least (i) the location-determination information of the first type or (ii) the location-determination information of the second type. At least some of the selected location-determination information may be used to estimate a location of the WCD.

Abstract: Described is a compact focal plane shutter system adapted for large-format exposure shutters. The focal plane shutter includes at least one multi-segmented screen having multiple rigid blades. Each blade can be moved at a different velocity. By using multiple blades, the rotational inertia about a drive axis can be reduced compared to a conventional single screen shutter system, thus a greater acceleration can be achieved with the same amount of torque about the drive axis. Using smaller blades allows for greater acceleration, resulting in faster shutter speeds to support a wider range of applications. Additionally, the overlap between blades of a multi-segmented screen in an open position is greater than the overlap of the blades in a closed position, providing a compact system. A drive mechanism linearly translates the blades of the multi-segmented screen between the open and closed positions.

Abstract: The present invention is directed to a cutting apparatus, which includes an s-shaped blade, for cutting a foodstuff to form a concave, tapered wedge product. The cutting apparatus includes a cylindrical housing member, a ring member, which receives and holds the s-shaped blade, and a base member affixed to the cylindrical housing member. The cylindrical housing receives at least one ring member, typically several. The several ring members, each receiving and holding an s-shaped blade, are stacked together. One or more ring members in the stack can be rotated in order to adjust the angles between the blades. By adjusting the angles between the blades, the size and dimensions of the cut foodstuff can be modified. Typically, the apparatus will be used as part of a high speed processing line.

Abstract: A pressure sensitive cursor control suitable for applications that include cellular phones and personal data assistants includes a pressure sensor array suitable to detect a human fingerprint. Cursor control is provided by subtle finger movement. Sequential images of the finger are captured and compared to determine planar movement or data entry. Performance may be improved by sampling zones within the captured image and comparing the zones with those in an earlier image. Performance could also be improved by subsampling the array. While the full resolution of the pressure-sensing array is needed to capture ones fingerprint and execute an authentication function only a subsampled image from the array is needed to derive meaningful navigation data. The pressure sensor array is designed on a glass substrate in order to drive down the unit cost.
