Title: Injection device with means for removing the syringe boot
Inventor: JENNINGS DOUGLAS
IPC: A61M5/20
Filed: 2006-06-01
Abstract: An injection device 110 has a housing 112 and a cap 130. The injection device houses a syringe 114 having a needle that is covered by a boot 118 to preserve its sterility in transit. The boot can be connected to the cap 130. The cap has grip means which may be a pair of arms 138 with a hook means 139, the syringe boot may be received between the arms and the hook means grip at the open end of the boot. A retention means which may be a ring shaped portion 140 has a groove (150) on its inner surface, the arms 138 of the grip means have a corresponding ridge (152). The ridge and the groove interlock to clamp the arms together and thereby clamp the cap to the syringe boot. The ring shaped portion 140 may have feet 144 (figure 7) that extend through the closed end of the cap (figure 5) and can be depressed to disengage the ring from the arms and allow them to splay out releasing the boot.

Title: Estimating the output current of a switch mode power supply
Inventor: PIPER JOHAN
IPC: G01R19/00
Filed: 2006-07-07
Abstract: Primary side sensing is used to estimate and to regulate the output current of a switch mode power supply (SMPS) comprising a transformer 21, a primary winding connected to switch 31 and a secondary winding connected to an output. An averaged primary current signal CS, a signal T0 representing the transformer charging time and a signal T1 representing the transformer discharge time are used to estimate output current OC, and to regulate it from an error signal ERR that is derived from a desired output current OCT. The sensed primary current CS, the charge signal T0 and the discharge signal T1 may be averaged over a switching cycle of the SMPS by low pass filters (figs 6-8, 12-14). The output current may be calculated by dividing the average primary current, multiplied by the discharge signal, by the charge signal, by means of either a delta-sigma circuit (fig 9) or a trans-linear circuit (fig 10). The charge time (fig 4, T0) may be the on time of switch 31 and the discharge time (fig 4, T1), when current is flowing through the secondary, may be found by comparing a sensed voltage VS from an auxiliary winding of transformer 21, or from the primary winding (fig 2). with the output voltage OV derived by an output voltage model (fig 5, OVM).

Title: Flapper opening mechanism
Inventor: DRUMMOND STEVEN J
IPC: E21B34/14
Filed: 2005-04-07
Abstract: A valve assembly comprises a flapper element and a valve opening assembly that will mechanically open the flapper element. The valve opening assembly is particularly valuable where the flapper element fails to open in response to normal hydraulic opening techniques. The valve opening assembly includes a valve opening sleeve having a generally hemispherical cross-section and an opening portion that presents a pair of opening shoulders. The opening shoulders engage lugs on the flapper element so that movement of the opening sleeve will urge the flapper element to an open position. The valve assembly may be run into the wellbore with the flapper element in the open position, rather than having to be closed, as with a number of conventional valve assemblies.

Title: Triangle waveform generator for a PWM amplifier
Inventor: STANLEY GERALD R
IPC: H03K4/06
Filed: 2006-10-10
Abstract: A triangle waveform generator comprises a capacitive element 302, a regulator 306,309 and a control circuit 303. The regulator 306,309 is configured to charge the capacitive element 5302 in responsive to a first control signal and to discharge the capacitive element in response to a second control signal. The control circuit is responsive to a reference waveform 344,346 to generate the first and second control signals. In one example, the control circuit generates the first and second control signals in response to the amplitude, frequency, phase, and symmetry of the reference waveform. A triangle waveform generator can generate first and second triangle waveform signals based on phase and frequency of respective first/second reference signals generated by a reference waveform generator and an interleaved PWM amplifier can generate interleaved PWM pulses in response to an input signal and the first and second triangle waveform signals to drive a power stage.

IPC: F16H59/08
Filed: 2008-05-01
Abstract: A method and apparatus for controlling a shift-by-wire transmission comprises providing a multi-stable selector 17 which via an indexing mechanism 24 provides a peak and trough force feedback to a driver so as to enable the driver to perceive a transition from one stable position to another. An output from at least one senor 18 is calibrated such that, when the selector 17 is located at any one of the peak force feedback positions, a single from the sensor 18 always results in an electronic controller 20 selecting a drive mode, e.g. reverse or forward, in the transmission.

Filed: 2009-03-18
Abstract: The signature of a seismic source array 14 is determined by determining a notional signature of at least one source 15 of an array of n seismic sources 15, 15' from measurements of the emitted wavefield from the array made at 2n independent locations 16a, 16a', 16b, 16b' and from the relative positions of the sources 15, 15' of the array 14 and the 2n independent locations 16a, 16a', 16b, 16b'. Seismic data acquired is then processed taking account of the determined notional signature to determine one or more parameters of the Earth's interior. Sensors are placed at the 2n independent locations 16a, 16a', 16b, 16b'. Two sensors 16a, 16b may be associated with each source 15. The sensors may be placed at different distances from their respective sources. The sensors may be placed in the near-field.

Title: Transient overvoltage protection for cascode transistors in CMOS output circuits
Inventor: RIEN MIKAEL
IPC: H03K19/003
Filed: 2009-04-20
Abstract: An output driver comprising low voltage transistors provides high voltage logic outputs. During a high-to-low output transition the source voltage of the cascode transistor 120 is rapidly reduced by the NMOS pull-down device 125, but the drain potential remains high until the output node 130 discharges, resulting in an excessive drain-source voltage across the cascode transistor 120. To improve transient voltage distribution across the output transistors 120,125 and so reduce gate breakdown and hot carrier injection effects, the gate bias for cascode transistor 120 is temporarily raised (170,160,155,165) during a high-to-low output transition. The voltage at the source of cascode transistor 120 may be limited by a source follower clamp. Analogous techniques may be used in the pull-up circuit (figures 5 and 6), the source follower clamp assisting turn-on of the PMOS cascode device (415, figure 6).
