Title: Method and apparatus for determining bit error rate in a sampled data system
Inventor: KOST ROBERT E
IPC: G11B20/18
Filed: 1998-08-27
Abstract: A system determines bit error rate in a sampled data system having a disc (112) formed of a magnetic medium and a data head (126) for writing data on the disc (112) and retrieving data from the disc (112). A pattern is written on the disc (112) which includes isolated instances (248) associated with a predetermined event. The pattern is retrieved from the disc (112) and the isolated instances (248) are combined to obtain a representative instance s<SB>av</SB>(n) having a reduced media noise component. The representative instance s<SB>av</SB>(n) is combined with each of the isolated instances (248) to obtain noise sequences. An autocorrelation component (R) is obtained based on the instances read from the disc (112) and the noise sequences. A channel filter is developed having an impulse response h(n) based on the representative instance and based on the channel requirements for a predetermined channel model. A representative instance is passed through the filter to obtain a filter output sample (smp), and an error value indicative of the bit error rate is determined based on the filter output sample and the autocorrelation component (R).

Title: Charging of mobile phone battery based on state of backlight function
Inventor: TAKENAKA HIDETOSHI
IPC: H04W52/00
Filed: 2000-02-24
Abstract: Radio communication equipment is provided which is capable of reliably completing a charge of a battery at a proper charging capacity and without causing deterioration of the battery regardless of whether or not a backlight function is continuously used at the time of charging. When a portable telephone starts charging, a CPU judges whether the backlight is turned ON. If the backlight is turned ON, a signal indicating that it is in the ON state is outputted from the CPU to a charging completion detecting circuits. The charging completion detecting circuit sets a threshold value indicating a charging completion current value to a threshold value ICUT2, which is higher than an ordinary threshold value ICUT1. A current detecting circuit detects a value of a current flowing from a charging terminal to a charging current detecting resistor and the charging completion detecting circuit judges whether a current value detected by the current detecting circuits has reached the set threshold value ICUT2. When the current value detected by the current detecting circuit reaches the set threshold value ICUT2, the charging is complete.

Abstract: A safety device for the lid 2, 4 of a cooking device such as an electric flying pan, has an engage device 20, 6 having a mouth 21, 60 fixed on an inner cover of the lid 2, 4, and a locking device in the form of a hook 11, 53 connected to the body 1, 3 of the appliance. The locking device hooks into the mouth 21, 60 of the engage device and hold the lid of the appliance closed. Part of the safety device may comprise a rotatable knob 10 which has to be pulled slightly in a direction away from the appliance in order to engage drive members (131, fig.2) with notches (110A and B, fig.2) on the hook member 11, and cause the hook member 11 to rotate out of engagement with the mouth 21 of the engage device 20. Alternatively, a safety button (52, fig.11) may be located on a push button (51, fig.11), which is pushed towards the appliance to push the hook member 53 away from the mouth of the engage member. The safety button 52 must first be slid transversely along the push button 51 to engage a safety projection 523 with a slide groove (504, fig.11), before the push button 51 is able to be pushed. A spring (41, fig.10) may be located at the hinge of the lid and the appliance, to normally bias the lid open. Elastic means (22, fig.7) may alternatively be located on the inner wall of the lid, which locates in an elastic groove (23, fig.7) on an inner wall of the appliance, and pushes the lid open a little when the hook 11, 53 is disengaged.

Title: Asymmetric compact for drill bit
Inventor: KLOMPENBURG GREG VAN
IPC: E21B10/16
Filed: 2002-11-01
Abstract: A roller bit has asymmetric compacts to increase the number of compacts in certain rows, in particular the heel row and the adjacent row thereto. The compacts are of tungsten carbide and have a cutting end axis and a barrel axis. The barrel axis 51 intersects the cutting end axis 57 at an obtuse angle. In the heel row, the barrel axis of the compacts is rotated to have less inclination than the cutting end axis. That is angle 53 is less than angle 59. In the adjacent row, each of the compacts has a barrel axis that is rotated to have more inclination than its cutting end axis and more inclination than the barrel axes of the heel row. That is angle 69 is greater than angle 73 and angle 69 is greater than angle 53. Also, the adjacent compacts in the heel row may be alternately angled in a similar manner fig 6. The same may be applied to the nose row 125 fig 10. Details are also given where the barrel axis and the cutting end axis are aligned but the alignment of the heel compacts and the adjacent row are inclined. In this case the surrounding area of the compacts is relieved figs 11-16.

Title: A component position indicating system
Inventor: WAIN ROBERT EDWIN
IPC: B60N2/90
Filed: 2003-01-13
Abstract: A component position indicating system which provides an indication when a first component is at the same position relative to a second component as it was at some historical reference time has a cable 11, fixed to the first component and a sheath 6 which surrounds part of the cable 11 and is connected to the second component. In this way relative movement between the first and second components produces movement of the cable within the sheath. One end of the cable 6, is wound around a cable drum 7, which is freely rotatably mounted in a chassis 2 such that movement of the cable 11 within the sheath 6, causes cable to wind onto or off of the drum 7 causing rotation of the drum 7 in the process. Sensing means senses the resulting movement of the drum 7 and records an output characteristic indicative of the position of the drum 7 relative to the chassis 2 so as to enable a particular relative position between said first and second components to be identified and accurately reproduced.
