Title: Power supply clamp for a smartcard
Inventor: GAY MICHAEL JOHN
IPC: G05F1/613
Filed: 1997-11-01
Abstract: A personal data carrier or smartcard operating in contactless mode has a tuned circuit 22, 24 which receives a transmitted signal and develops an AC voltage at nodes 26, 28, NMOS transistors 30-36 forming a full wave rectifier having an input connected to nodes 26, 28 and a DC power supply output connected across lines 38, 40, and a clamping circuit 46-50 having a transistor 50 coupled across the AC nodes 26, 28 and controlled in response to the DC power supply voltage across lines 38, 40 to limit/regulate the DC voltage. Placing the clamping transistor 50 across the AC nodes 26, 28 instead of across lines 38, 40 avoids loading the rectifier by the transistor. Transistor 50 is controlled by a transconductance amplifier 46 which compares the DC supply voltage with a reference and has an output coupled to an integrating capacitor 48 to form a regulation loop which is relatively slow, thereby aiding recovery of data amplitude modulated on the AC signal across nodes 26, 28. Diode-configured transistors 60, 62 demodulate the data from the AC nodes 26, 28, rather than from the output of rectifier 30-36. The transistors 30-36 of the rectifier also provide electro-static discharge protection against ESD events causing node 26 or 28 to become positive or negative relative to DC supply line 38 or 40. A second regulation loop with a fast response time may additionally be provided (Fig.4) for situations where the loop 46-50 is not fast enough - eg. when a magnetic field is suddenly applied. The fast loop has a comparator (70) which responds to the DC supply voltage and controls transistors (72), (74) respectively connected between DC line 40 and AC node 28 and between line 40 and AC node 26. The fast loop is also effective when the card is in direct physical contact with a reader connected to apply a supply voltage directly to DC line 40.

Patent GB-2325013-A (GB)
Title: Shroud for a well screen
Inventor: MCCONNELL HOWARD T
IPC: E21B43/08
Filed: 1998-01-30
Abstract: A shroud for covering a well screen (S) comprises a tubular member having circular holes (10) in its wall through which well fluid can flow into the annulus between the shroud and the screen (S) and an arcuate strap (12), the ends of which, are attached to the shroud on opposite sides of each hole forming lateral openings (14, 16). Each strap (12) has a width less than the diameter of the holes and extends into the annulus between the shroud and the screen. Fluid enters the cylindrical openings in the shroud in a helical fashion and contacts the concave surface of the straps (12). The circular helical flow of the fluid is enhanced so that the fluid enters the annulus between the shroud and the well screen in a circular flow pattern generally parallel to the longitudinal axis of the screen, which causes the fluid to flow into the annulus generally parallel to the outer surface of the well screen. This creates a more efficient flow pattern than a perpendicular angle and protects the screen from being damaged by any solid particles carried by the well fluid hitting the screen directly.

Title: Semiconductor device simulation method and simulator
Inventor: LUI BASIL
IPC: G06F17/50
Filed: 1999-06-15
Abstract: An automated simulation method for determining the enhanced generation-recombination rate due to trap-to-band tunnelling in a semiconductor device using the Dirac coulombic tunnelling integral and to a simulator for carrying out the method are disclosed. The method and simulator are, for example, particularly useful in the modelling of characteristics such as leakage current in polysilicon TFTs, which leakage current can, for example, seriously degrade pixel voltage in active matrix display devices. The simulator embodies the method, which method comprises the steps of: assigning the variable C to the ratio of the Poole-Frenkel barrier lowering energy (    E<SB>fp</SB> ) divided by the energy range for which tunnelling can occur (    E<SB>n</SB>); assigning the value (C + 1)/2 to a variable v and performing a second order Taylor's series expansion of the Dirac coulombic tunnelling integral around v to determine a maximum value (u<SB>max</SB>) for the variable u of the integral; determining if the value for u<SB>max</SB> is less than C, is between C and 1 or is more than 1; assigning the value of C to the variable v if u<SB>max</SB> is less than C; assigning the value of u<SB>max</SB> to the variable v if u<SB>max</SB> is between C and 1; assigning the value of 1 to the variable v if u<SB>max</SB> is more than 1; reducing the Taylor's series expansion of the Dirac coulombic tunnelling integral to an error function; reducing the error function to simple exponential functions by applying rational approximations to the error function; and calculating the enhanced generation recombination rate due to trap-to-band tunnelling in a semiconductor device using the said simple exponential functions.
