Abstract: A controller receives an M-bit input and generates, in response, an S-bit upper range binary data feeding S-bit high range DAC and an R-bit lower range data feeding an R-bit low range DAC. The controller detects transition points in the M-bit input and in response, adds a transition data to the S-bit data equal to at least one least significant bit of the S-bit data and subtracts a value from the R-bit data equal to the transition data. The transition points and the transition data are detected and added at points avoiding such transitions at a full scale value of the R-bit data.

The host state sensing logic can include program code enabled to adjust a threshold value for permitting message interruptions for messages having assigned priorities beyond the threshold value.

Abstract: The utility model discloses a negative ion air purifier, comprising an electrostatic field-generating module and a voltage boost circuit. The voltage output end of the voltage boost circuit connects with the voltage input end of the electrostatic field-generating module. Said electrostatic field-generating module includes anodes and cathodes that are arrange alternately and equidistantly. A frequency conversion and voltage regulation module is further added, whose voltage signal sampling end connects with the voltage output end of said voltage boost circuit and whose control end connects with the voltage signal input end of said voltage boost circuit, thus making the device adapted to the fluctuation of the mains electricity between 180V to 240V and perform its functions steadily, and overcoming the disadvantages of existing products, such as the proneness to burnout and stop, unstable release of the ion flow, big noise and the difficulty in keeping effective.

Abstract: The present invention facilitates communications between a first network and a second network using an information routing device having an auto-configuration feature. The auto-configuration feature negotiates what authentication protocol will be used when the networks transfer information. Once the authentication protocol is negotiated by the device, the device intercepts and stores information transferred between networks. In this manner, the device can emulate a first network when coupled to a second network by providing the necessary stored information directly to the second network, and vice versa.

Abstract: Apparatus and methods for monitoring and controlling network activity of network appliances are provided, in which the network activity is transmitted to at least one controlling mobile communications device such as a cellular telephone or wireless telephone-enabled personal digital assistant. Internet access filtering technology is provided wherein Internet access of a monitoring network appliance may be selectively blocked based upon predefined rules, and information regarding Internet access activities, whether blocked or not, may be redirected to multiple controlling mobile communications devices for review based on other predefined rules. The predefined rules may be modified dynamically by sending a command from the controlling mobile communications device to the monitoring network appliance.

Abstract: Apparatus and methods are provided for selectively providing telephone service that is either PSTN-based on Internet-based using a standard analog telephone circuit. In a first embodiment, the apparatus comprises a hardware module and associated software for coupling a personal computer or Internet appliance and a standard analog telephone. The apparatus includes a DTMF interface circuit, a subscriber line interface circuit, a ring detection circuit, and an interface circuit for interfacing with the PC or Internet appliance. The apparatus permits the analog telephone to be toggled between an Internet-based telephone mode and a PSTN-network mode by inputting a predetermined sequence of DTMF digits. In alternative embodiments, the apparatus comprises a processor, modem and optionally, analog telephone circuit, to provide a stand-alone or partially-integrated device capable of selectively switching between PSTN-based and Internet-based telephony services.

Abstract: A method for monitoring and controlling network activity of one or more network appliances in real-time is provided. The network activity of a network appliance may be monitored by the network appliance itself or, if the network appliance is in a LAN, by a network gateway in the LAN. The network activity is transmitted to one or more controlling network appliances based on which type of IP address is assigned to the monitoring network appliances and the controlling network appliances. The controlling network appliances control the network activity of the monitored network appliances by sending a command to the monitored network appliances with or without user intervention. The monitored network appliances execute the command to control their network activity in real-time.
