The invention provides methods for sequencing a polynucleotide comprising stopping an extension cycle in a sequence by synthesis reaction before the reaction has run to near or full completion.

The present invention provides a displacement detection apparatus uses short scales and can provide a long measurable range comparable to a single long scale with a short bed length. The displacement detection apparatus includes a scale, a first head and a second head adapted to detect periodic analog signals of a plurality of different types, a first processing section and a second processing section that detects the first differential value and the second differential value between the immediately preceding positional data and the current positional data obtained by sampling the periodic analog signals of a plurality of different types, a switching section that selectively switches from the first differential value to the second differential value or vice versa, a scale position detection section that detects the scale getting to a predetermined position relative to the first head or a predetermined position relative to the second head, a switching control section that causes the switching section to switch from either of the differential values to the other in response to the detection of the scale getting to the predetermined position, and an addition section that adds the first differential value or the second differential value selectively switched by the switching control section and outputting it as positional information.

An image processing apparatus for tracking faces in an image stream iteratively receives a new acquired image from the image stream, the image potentially including one or more face regions. The acquired image is sub-sampled (112) at a specified resolution to provide a sub-sampled image. An integral image is then calculated for a least a portion of the sub-sampled image. Fixed size face detection (20) is applied to at least a portion of the integral image to provide a set of candidate face regions. Responsive to the set of candidate face regions produced and any previously detected candidate face regions, the resolution at which a next acquired image is sub-sampled is adjusted.

In a wireless device monitoring system including a mobile telephone and an authentication apparatus, a controller of the authentication apparatus repeatedly executes a distance detection processing based on a received level of a received wireless signal and an authentication processing based on authentication data included in the received wireless signal continuously at a first communication interval T1 and a second communication interval T2, respectively, and outputs an alarm signal or executes a predetermined control processing when a true counterpart electronic apparatus is not present or when the true counterpart electronic apparatus is apart from the electronic apparatus by a distance longer than the predetermined threshold distance. When a first communication time T11 for the distance detection processing is shorter than a second communication time T12 for the authentication processing, the T1 and the T2 are set to satisfy T1<T2.

Improved methods and devices are provided for detecting and / or predicting the onset of an undesirable physiological event or neural state, such as an epileptic seizure, to facilitate rapid intervention with a treatment therapy such as neurostimulation or drug therapy. The methods and devices involve monitoring the patient's body temperature, preferably by an implanted temperature sensor, to detect a change in a body temperature parameter over a first time period. The temperature parameter change may comprise an increase or decrease in the patient's body temperature over a first time period, time rate of change of body temperature over a first time period, a moving average temperature over a first time period, an increase or decrease in body temperature exceeding a target temperature over a first time period, an elevated or reduced body temperature over first time period, or a temperature stability parameter over a first time period. The sampling period at which body temperature measurements are made may be changed manually or depending upon a sensed body parameter, including temperature. When a parameter change is detected that exceeds a threshold, neurostimulation therapy is delivered to a neural structure of the patient.
