Abstract: A method of performing a frequency correction of a radio module. Multiple samples of frequency data during a quiescent portion of the base station transmission is taken to estimate the amount of frequency correction needed. An embodiment applies the frequency data to a median filter to eliminate invalid data. Next, a new reference frequency is applied to a radio transceiver in the radio module to provide the frequency correction. If the frequency was corrected by greater than a pre-determined amount, the process performs a large shift frequency correction, including verifying that the first frequency correction was satisfactory and verifying that the radio transceiver is able to receive data after the frequency correction has been performed. If the frequency was corrected by smaller than a pre-determined amount, the process performs a small shift frequency correction, including updating a total of all frequency corrections made since a stored reference frequency was updated.

Abstract: Systems and methods for a user to receive dynamic business information on a wireless communication device via a wireless connection are presented. The wireless communication device can be a hand-held personal computer, a paging device, a wireless telephone, or other wireless communication device. Dynamic business information comprising subscription-based content that is tailored to an individual is delivered to the device. The systems and methods provide a mechanism for setting personalized thresholds for data items maintained by an application. These thresholds can then be used to enact an event (or alert) via the application when the threshold is met. For example, the alert can be an audible sound or a display of a message that appears on the wireless communication device. As a further example, the alert can comprise an e-mail received on the wireless communication device.

The continuous holding slots of the preferred embodiment of the handle include multiple contoured compartments for holding an inserted hexagonal wrench. Each contoured compartment is formed about a corresponding receiving hole. A lock is positioned over the contoured compartment to irremovably confine the short leg of the hexagonal wrench within the contoured compartment.

Abstract: Frequency correction of a radio module. An estimate is made of the amount of frequency correction needed while applying an original reference frequency. If the frequency correction needed is greater than a pre-determined amount, a large shift frequency correction is performed, including applying a new reference frequency and verifying that the large shift frequency correction is satisfactory. If the large shift frequency correction is unsatisfactory, the original reference frequency is restored. If the frequency correction needed is smaller than a pre-determined amount, a small shift frequency correction is performed, including applying a new reference frequency and updating a total of all frequency corrections made since a stored reference frequency was updated.

Abstract: A jump rope simulator for aerobic and anaerobic exercise having a hand-held unit comprising a handle, a base length connected to the handle, and one or more concatenated extension lengths attached to the base length. To exercise, the user grasps one or two units, imitates the motions of swinging a conventional jump rope, and jumps up and down, but there is no risk to the user of tripping over a rope as with a conventional jump rope. If the user desires, two units may also be linked together with an easily attachable connector to form a device similar to a conventional jump rope. A user can quickly convert between the two configurations of the jump rope simulator.

Abstract: A probe for an array of interconnecting leads between a PCA and an IC has one or more contacts extending laterally from or plated upon one or more arms formed of a flexible printed circuit, and connected by traces along the arm(s) to a header that itself affords connection to measurement equipment. The flexible printed circuit is thin enough to loosely slide between the top of the PCA or PCB and the bottom of the IC. The arm or arms is/are narrow enough to slide between the adjacent leads forming the array, while the normally flat contacts will successively interfere with, to engage and electrically contact, consecutive layers of leads as the probe is progressively inserted. An arm is not so stiff that it cannot yield by a slight compressive warping as the contacts encounter leads. Indexing may be ‘by feel’ or by visible indicia along a top surface of the probe or by a reticle device that moves over the top of the IC, which then has a pattern of indicia corresponding to lead location.

The first and second pairs of contacts electrically couple the probe accessories between test points and test instruments.

Abstract: A method for measuring overlay in semiconductor wafers includes a calibration phase in which a series of calibration samples are analyzed. Each calibration sample has an overlay that is known to be less than a predetermined limit. A difference spectrum for a pair of reflectively symmetric overlay targets is obtained for each calibration sample. The difference spectra are then combined to define a gross overlay indicator. In subsequent measurements of actual wafers, difference spectra are compared to the overlay indicator to detect cases of gross overlay.

Abstract: A calibration method suitable for highly precise and highly accurate surface metrology measurements is described. In preferred embodiments, an optical inspection tool including a movable optics system is characterized in terms of position and wavelength dependent quantities over a range of motion. Once the position-dependant quantities are determined at various wavelengths and positions, they are stored and used to interpret data from test wafers having an unknown metrology. Free of position-dependent variations and other information pertaining to the measurement system, the accuracy of the resulting wafer measurement more closely matches the precision of the tool than existing techniques. In particular embodiments, a portion of the characterization of the optical system is accomplished by using tilted black glass to provide a non-reflective reference.
