20120144918 | LONGITUDINAL RESONATING MODE INERTIAL MASS SENSING SYSTEMS - The subject invention provides improved means to measure mass collected on a sample collection surface in real time. A resonant structure is used as the “scale” to determine the mass in real time. The invention employs a membrane, or collection substrate, on the end of a resonant structure resonating in the longitudinal direction. A structure resonating in the longitudinal mode offers a considerably higher resonant frequency than the same structure in the bending mode. The higher the resonant frequency, the more resolution in the frequency of oscillation is available to determine the mass of the collection surface or membrane. The present invention implements this attribute in connection with such a structure. | 06-14-2012 |

20100258357 | Inertial Microbalance Filter Assembly - A low tare weight filter system is disclosed. The low weight makes the system especially advantageous for use in inertial microbalance instrumentation where small variations in mass must be accounted for to deliver accurate results. Moreover, the assembly is constructed to permit the filter collector to flex and stretch over a complimentary body incorporated in a filter support base and securely fasten to the same. Such use offers further advantages for instrument performance. It insures consistent apposition and long-term stability in the contact between the filter media and its reference surface. | 10-14-2010 |

20110126739 | Portable, Collapsible, Workstation Tray Table Apparatus - An apparatus includes a surface panel for supporting objects in a first workspace. The surface panel includes a removable plug having a first flat surface and a second surface comprising rectilinear fingers for supporting devices in a generally upright position. A frame having a top side and a bottom side holds the surface panel above the top side and enables the surface panel to be positioned at a plurality angles relative to the frame. Appendages joined to the frame and deployable from the frame enable the frame and the surface panel to be supported a distance above a surface, where the distance is sufficient for enabling a second workspace between the frame and the surface. | 06-02-2011 |
20140311388 | Airplane Tray CIP - A portable workstation includes a top panel having a distal edge and a lower surface. Also included are a bottom panel having a proximal edge and an upper surface, and a middle panel connected by a hinge to the distal edge and to the proximal edge. The middle panel and the bottom panel are spanned by a first folding support. The middle panel and the top panel are spanned by a second folding support, so that the first folding support and the second folding support hold the top panel, the bottom panel. and the middle panel in a predetermined, expanded position. | 10-23-2014 |

20130169327 | Charge-to-Digital Timer - The charge-to-digital timer apparatus and method disclosed herein estimates the elapsed time between two signals, e.g., a start signal and a stop signal. To that end, at least a capacitive load is charged with a known current to generate a load voltage. Subsequently, a first voltage is ramped in a plurality of discrete voltage steps associated with a plurality of known capacitances until the ramped voltage satisfies a predetermined criterion relative to a second voltage. The elapsed time is determined from the discrete voltage steps, one of the first and second voltages, the known current, and the known capacitive load. | 07-04-2013 |
20130169455 | Calibration of a Charge-to-Digital Timer - A calibration method disclosed herein calibrates at least one of a capacitive load and a charging current controlling a charge-to-digital timer (CDT). In general, the disclosed calibration method measures multiple calibration phases based on start and stop signals separated by a known time difference, and therefore having a known phase, and adjusts at least one of the capacitive load and the charging current of the CDT based on the measured calibration phases. In so doing, the disclosed calibration method reduces power dissipation and peak supply currents over the frequency range of the CDT. | 07-04-2013 |
20130169457 | Resistive/Residue Charge-to-Digital Timer - A resistive/residual Charge to Digital Timer (RCDT) provides efficient, accurate measurement of short time delay between two signals, by converting the time delay to current, and measuring the charge integrated by a capacitor over a duration. In one embodiment, in quantizing this charge (measured as voltage), a residual charge is maintained cycle-to-cycle. This allows for implementation of a Noise shaping Charge to Digital Timer (NCDT), providing improved resolution over a plurality of measurement cycles. The RCDT/NCDT is particularly (but not exclusively) well suited for phase error detection in a Digital Phase Locked Loop. | 07-04-2013 |
