Title: Voltage clamp for flyback converter
Inventor: CHENG KIM TUNG
IPC: H03K17/0814
Filed: 1996-10-30
Abstract: A voltage clamp for single-ended flyback converter provides partial leakage energy recovery and noise suppression, the voltage clamp being an improved version of a conventional RCD (resistor, capacitor, diode) lamp. The voltage clamp comprises two switches 304 and 307 with different turn-off speeds. A capacitor 305 and two resistors are included. One resistor 307 is in parallel with capacitor 306 and the other resistor 308 is in parallel with the switch 304. The faster switch 304 enables at least partial recovery of energy dissipated in a clamp resistor 306 immediately after turn OFF of a main switch 302. As the switch 307 opens after the switch 304 closes, noise in the circuit is suppressed by a damping resistor 308 which thereby remain effectively in a current path after the switch 304 has re-opened.

Title: Electricity consumption metering with transformer phase angle error compensation
Inventor: LESTER GERALD
IPC: G01R21/133
Filed: 1996-11-12
Abstract: A method or means of metering electricity consumption comprises taking power measurements and compensating said measurements for a phase angle error introduced by transformer means 6 involved in the measuring process. The transformer means 6 may be a current and/or voltage transformer with a predetermined phase angle error characteristic. The meter may use current and voltage measurements i. v to determine real and reactive power values PR(meas), PX(meas) which may be compensated, using compensating means 20 to 28, to provide true real and reactive power values PR, PX. When more than one transformer is involved: respective, average or the difference between phase angle errors may be employed.

Title: Controlling ventilation apparatus by humidity measurement
Inventor: HUDSON RAYMOND JOHN
IPC: G05D22/02
Filed: 1996-12-31
Abstract: Apparatus for ventilating a building or room space switches on a ventilator in response to humidity measurement by comparing the current measured value of humidity with the average of the humidity readings over a period of time. A second humidity reading is made after the ventilation has been operating for a period of time, and the time for which the ventilation is switched on is determined from the difference between the second reading and the average reading. As described, the ventilation apparatus 1 is controlled by microprocessor 6 which receives inputs from humidity sensor 2 and temperature sensor 7.

Title: Trolley stabiliser
Inventor: MACDONALD MICHAEL IAN CHARLES
IPC: B60B33/02
Filed: 1997-03-14
Abstract: A trolley, or a unit for use with such a trolley, is stabilised in order to ensure straight running. The stabilising means may be a non-castoring wheel 21 arranged for movement between a ground engaging position and a non-ground engaging position depending upon the motion of the trolley. Alternatively swivelling of a castor around a vertical axis may be prevented and permitted depending upon the motion of the trolley. The aspect of the motion of the trolley affecting the stabilising means may be forward velocity, such that the non-castoring wheel engages the ground when the trolley exceeds a predetermined forward velocity; or a cam plate 22 secured to a castoring wheel 17 may engage a cam follower 23 when the castoring wheel is in the straight ahead position, said cam follower moving the non-castoring wheel into a ground engaging position, the wheel being spring loaded by spring 24 out of engagement with the ground; or such a cam plate may engage a cam follower (30 figure 5) which acts as a brake against the rotation of the cam plate; alternatively the time of forward movement may affect the stabilising means. The non-swivelling wheel may be associated with a castor.

Title: A hand held bag holder using clips as securing means
Inventor: IMMS JOHN VICTOR
IPC: B65B67/12
Filed: 1997-10-10
Abstract: A hand held bag holder 10 for maintaining the mouth of a bag in an open position typically for use in collecting garden debris comprises a frame 12, typically circular, and one or more clips 16 which are generally U-shaped and secured onto the frame 12 in a snap fit engagement. The legs 24 and 26 of clips 16 secure the bag by straddling the frame 12 and clamping the upper folded over portion of the bag against the (cross sectional) surface of the frame 12. The mouth defined between legs 24 and 26 of 16 is narrower than the width of the frame member 12 so that pressure must be applied to 16 in order to effect engagement with 12. The frame may possess a circumferential groove on its inner and outer surfaces to engage the legs 24 and 26 of clips 16. Spaced apart sections 20 of frame 16 with reduced cross sectional area and of slightly longer length may be provided for fixing the location of the clips at equidistant positions along 12. Alternatively, a single clip of very similar circumferential length to 12 may be provided so that the bag can be secured along practically the full length of 12. Handle 14 and frame 12 are preferably formed in one piece from a plastic material.

Title: In-circuit emulator with internal trace memory
Inventor: HIGASHIDA MOTOKI
IPC: G06F11/36
Filed: 1998-08-14
Abstract: An in-circuit emulator (ICE) 1 for supporting debugging of a system which includes a processor has an internal trace memory 14 and a bit-width convertor 15. The internal trace memory 14 is embedded in an ICE CPU 2 and stores CPU internal signals fed from an emulator CPU core 11 that executes the same operations as a CPU (not shown) of the system to be debugged. The bit-width convertor 15 converts a CPU internal signal, read out of the internal trace memory 14, into a plurality of reduced bit-width signals, and supplies them to an ICE controller 4 outside the ICE CPU chip in multiple cycles. This configuration removes the restriction imposed (by the number of terminals of the ICE CPU chip 2) on the number of bits of the CPU internal signal which can be output in parallel, and overcomes the difficulty involved in sampling the internal CPU signals by the trace memory even as the operation frequency of the ICE CPU increases.

Filed: 1999-01-14
Abstract: An antenna system is disclosed for transmitting and receiving electromagnetic signals, comprising a backplane 12 (fig 9, 212) having a length and a vertical axis along the length. A plurality of dipole radiating elements 11a-f (fig 9, 211a-f) project outwardly from a surface of the backplane. Each of the elements includes a balanced orthogonal pair of dipoles 18,20,22,24,26,28 (fig 9, 218,220,222,224,226,228) aligned at first and second predetermined angles with respect to the vertical axis, forming cross dipole pairs. An unbalanced feed network 30 (fig 9, 230) extends along the backplane and is connected to the radiating elements. A printed circuit board balun 33 (fig 9, 233) is attached to each of the dipoles. The antenna can also include a parasitic element (34) positioned along the vertical axis such that primary electromagnetic fields induce currents on the parasitic element, these induced currents re-radiate secondary electromagnetic fields which cancel portions of the primary electromagnetic fields, thereby improving isolation. The slant angles -a and +a need neither be equal to each other nor equal 45.

A further aspect relates to a secondary control circuit 40, such as a DC/DC converter, providing an operating voltage to the control circuit 34 at least on failure or drop in operating voltage for the control circuit 34. In a further aspect the control system is such that in the absence of or a drop in the motor supply voltage, field weakening is maintained, supplied by the voltage induced in the motor.
