Title: Limiting access to private networks in cellular communications systems
Inventor: WESTERBERG LARS ERIK
IPC: H04L12/56
Filed: 1998-09-15
Abstract: A mobile cellular communications system and method are disclosed, which limit access to private network cells (114) only to mobile terminals that are used by subscribers to those private networks. In cells belonging to the public network, only information about the public cells (122) is broadcast on the public system information control channels. This public cell (122) information is thus the only cell information that the non-subscribers' mobile terminals are able to receive. When a mobile terminal belonging to a subscriber of one or more private networks surfaces in a public cell (122), the public network transmits a radio link control message to that mobile terminal, which contains information about the candidate cells for selection associated with the private network(s) involved. The private network transmits system information via the private cell (114) to a subscribing mobile terminal about the private and public cells' neighboring cells (122). Consequently, the subscribing mobile terminal will regard the public network cells (122) and private network cells (114) as integral parts of the overall cellular system. Cells associated with private networks to which that mobile terminal's end user is a "non-subscriber" are thus "invisible" to that mobile terminal.

Title: Efficient coding of side information in a lossless encoder
Inventor: BRUEKERS ALPHONS ANTONIUS MARI
IPC: G10L19/04
Filed: 1999-12-24
Abstract: For "Super Audio CD" (SACD) the DSD signals are losslessly coded, using framing, prediction and entropy coding. Besides the efficiently encoded signals, a large number of parameters, i.e. the side-information, has to be stored on the SACD too. The side information comprises the prediction filter coefficients and the probability table which have been used for encoding, and which should be transmitted to the decoder. The smaller the storage capacity that is required for the side-information, the better the overall coding gain is. Therefore coding techniques are applied to the side-information too so as to compress the amount of data of the side information. The frames can be segmented, each segment having its own set of filter coefficients and probability table.

Abstract: It is an object of the present invention to provide a method and device which can efficiently use a battery used for portable electronic device without lowering quality of sound emission of a musical piece, an effect sound and so on. According to the present invention, in order to achieve both the longer battery life of the portable electronic device and better quality of the sound emission, an operation clock of the CPU of the portable electronic device and the processing wait time of image drawing are controlled dynamically. When there is no sound emission, the CPU is run at a low clock, and if there is a sound emission request, the CPU is switched to run at a high clock (ST7), and when the sound emission ends, the CPU is again made to run at a low clock.  Since changing the CPU clock also changes the speed of the screen drawing, it is arranged to that one does not feel any apparent clock change, by making the processing wait longer if the clock is high (ST6 and ST4), and making the processing wait shorter if the clock is low.

Abstract: In a refrigeration system (10), a multiple compressor system for maintaining the heat output constant while the outside ambient temperature continues to decrease. The present invention comprises a primary compressor (31) and at least one secondary compressor (32). The entire refrigeration system is sized for the primary compressor (31) operating while in the cooling mode. In the heating mode, the primary compressor (31) operates by itself until the outside ambient temperature (60) falls to a temperature within a particular range. Once this temperature range is met, a secondary compressor (32) begins operating in conjunction with the primary compressor (31) such that the mass flow of refrigerant through the system in the heating mode of operation is no greater than that of the primary compressor operating alone in the cooling mode. While the outside temperature continues to decrease, additional secondary compressors may be included to maintain a constant heat output. In the cooling mode, only a single compressor is required to operate the system. Each of the compressors may alternate with any other so that the lives of the compressors are preserved.

Abstract: A process for treating an aqueous liquid. The process includes: passing the liquid by force of gravity through a treatment area, the liquid having an upper surface exposed to ambient pressure; disrupting the flow of the liquid as it passes through the treatment area; and exposing the upper surface of the liquid as the flow is disrupted to UV light. Disrupting the flow includes directing lower portions of the liquid toward the surface of the liquid to bring such portions into contact with UV light. A process for treating an aqueous liquid in which the treatment process is monitored. This process includes passing the liquid through a treatment area to bring the liquid into contact with reflective walls submerged below an upper surface of the liquid, and exposing the upper surface of the liquid to light emitted from a UV light source such that UV light penetrates the liquid to strike the submerged reflective surfaces and to be reflected therefrom to emerge through the upper surface of the liquid. The process also involves determining the intensity of the UV light emitted from the light source, determining the intensity of UV light received by a UV light sensor trained to receive emergent light and determining whether the treatment has a predetermined effectiveness based on the intensity of the UV light emitted from the light source and the intensity of the UV light received by the sensor. Apparatuses for carrying out processes of the invention are also described.
