Title: Image encoding apparatus, image decoding apparatus, image encoding method, image decoding method, image encoding program recording medium and image decoding program recording medium
Inventor: KADONO SHINYA
IPC: H04N19/463
Filed: 1997-05-15
Granted: 2002-08-13
Abstract: Image signals or shape signals are encoded more efficiently than conversion techniques. A changed-picture element detector (2) receives an input signal (1) and detects such a picture element that changes in binary picture element value. A changed-picture element predictor (4) reads a reference image stored in a memory (3) and predicts changed picture elements of the input signal (1).  A differential value calculator (5) subtracts the output of the predictor (4) from the output of the detector (2) and a differential value rounding device (7) compares an allowance value (e) with a predicted error (D) and outputs a minimum value (x) (D-exD+e) at which the number of bits required for the encoding using the value (x) becomes the smallest. An encoder (8) encodes the output of the device (7) into an encoded signal (9) and a differential value adder (11) calculates a changed-picture element by adding the output of the device (7) to the predicted picture element predicted by the predictor (4). A  changed-picture element decoder (10) decodes each picture element value from the decoded picture elements specified by the predictor (4) to the changed-picture elements and stores the decoded picture element values in the memory (3).

Abstract: A device for limiting the flow of a fluid from a first region of a patient's body to a second region includes a primary passage for directing fluid from an inlet of the device to an outlet in response to the fluid flow rate being less than a predetermined level and a secondary passage for directing fluid from the inlet to the outlet in response to the flow rate being greater than or equal to the predetermined level. The secondary passage can be characterized as a tortuous flow path and presents a higher resistance to fluid flow than the primary passage. A detector is operative to close the primary passage in response to the flow rate reaching the predetermined level in order to force the fluid to pass through the secondary passage. With this arrangement, when the fluid flow rate reaches a level characteristic of overdrainage, the fluid is forced through the secondary passage in order to effectively reduce the fluid flow rate and prevent overdrainage. As soon as the flow rate decreases below the predetermined level, the primary passage opens itself automatically.

Title: Air heating system
Inventor: MENASSA CHERIF
IPC: F24H9/20
Filed: 1998-07-10
Granted: 2003-02-25
Abstract: An air heating system includes a duct containing an electric heating coil and a thermistor which is part of an electronic thermostat for controlling the heating coil. The thermistor is so located as to be directly exposed to heat radiated by the heating coil. The thermistor, in effect, acts as an airflow sensor so that the heating coil will gradually cool down and eventually shut off according to the air velocity in the duct. Heating is restored automatically once airflow in the duct has sufficiently cooled down the thermistor. Thus, the thermistor acts as an airflow sensor to modulate the heating capacity according to the quantity of air flowing through the duct.  The heating system can be used in a fresh air intake for a central air furnace or for a heat pump, for baseboard heating with a duct and fan or as a unit incorporated into a larger forced air heating system.

Abstract: A communication device locates a preferable wireless service provider in a multi-service provider environment using a frequency band search schedule.  Initially, the communication device registers with a less preferred service provider in a first frequency band. While remaining registered with the less preferred service provider, the device examines several frequency bands in the order specified by the frequency band search schedule. A frequency band is examined by dividing the frequency band into many sub-bands, and by locating the strongest signal above a threshold within the sub-band being examined. The examination continues until a second frequency band having a more preferred service provider is located. The communication device then registers with the more preferred service provider. The category of service provider may be identified and displayed on the communication device.

Abstract: The invention features a method for providing a user access to a secure application. The invention stores in an encrypted form the authentication information necessary to satisfy the authentication requirements of the secure application. When the user requests access to the secure application, the user is presented at his or her display with a request for authentication. The user must manipulate at least a portion of the symbol to respond properly to the authentication request. The user's manipulation(s) of the symbol(s) generate a CodeKey used to decrypt the encrypted stored authentication information into a result. After the result is created, it is provided to the secure application. If the result support's the secure application's authentication requirements (i.e., if the CodeKey has properly decrypted the encrypted stor ed authentication information), the user will be granted access to the secure application. The invention therefore provides a simple, secure and effective method for a user to gain access to a multitude of secure applications without having to recall a series of complicated passwords.

Abstract: Disclosed is a frequency-locked loop (FLL), which attempts to bring about frequency and phase synchronization between two signals over the control bandwidth of the loop: a reference signal and a voltage-controlled oscillator (VCO) signal. For example, the FLL employs a reference signal generated by a crystal oscillator of frequency .function. REF and a VCO signal generated by the oscillations of an unquenched SRG resonator with tunable resonant frequency .function. RES.  These signals are connected to the inputs of a phase/frequency detector (PFD) which produces output pulses in response to the relationship between .function.REF  and .function.RES. These pulses are applied to a loop filter (LF) which creates a voltage using some kind of charge-storage element. This loop filter voltage is a so-called error voltage whose value is used to control the frequency of the resonator to bring the reference signal and VCO signal into phase synchrony.
