Title: User invocation of services in public switched telephone network via parallel data network
Inventor: DUNN JAMES M
IPC: H04M3/42
Filed: 1997-10-28
Granted: 1999-07-11
Abstract: This invention allows customers and other users of the public switched telephone network (PSTN) to enable, disable or modify special services provided by the network. The PSTN is defined here as all equipment world wide (land-based, radio or other) enabling ordinary telephone users to connect to other telephone users, but excludes private telephone networks such as "tie line" systems maintained or leased by private enterprises. Presently contemplated actions can be taken independent of the state of the customer's telephone line (e.g. on-hook or off-hook), and usually involve use of equipment other than telephones and communication networks other than the PSTN (e.g. computers operating through the Internet and pagers operating through pager networks). The special services include existing services (call waiting, call blocking, call forwarding, etc.) and new ones (e.g. transferring an active call from a desk phone to a mobile cellular one without interrupting the call). Security firewalls, between the public and telephony application intelligence (TAI) systems that administer customer services within the PSTN, ensure that actions by unauthorized individuals do not interfere with or adversely affect telephone system operations. Authorized customer talking presently contemplated actions will not be able to adversely affect telephone system operations. The present system will work on information maintained at any level of an intelligent network hierarchy within the PSTN, including service nodes through which customer services are traditionally provided.

Title: Disk reproduction device and data slicing circuit
Inventor: OOKUBO MAMIKO
IPC: G11B20/10
Filed: 1998-06-25
Granted: 2000-06-11
Abstract: This is to provide a disk reproduction device and a data slicing circuit where a clock signal frequency inputted to an up-and-down counter continuously follows at a reproducing rate of EFM (Eight Fourteen Modulation) signal. Its phase is asynchronous with the EFM signal. A data slicing circuit 17 is provided with a clock signal generation circuit 8, which is used for generating second clock signal PLCK 2, in order to generate an EFM signal from an RF signal. PLCK 2 is asynchronous with the EFM signal. The data slicing circuit 17 frequency-divides the second clock signal by a frequency divider and generates a clock signal CK for counting. The frequency of the CK continuously follows the EFM signal reproduction rate; its phase becomes asynchronous with the EFM signal. The reference voltage control band for slicing an RF signal generated by different counter output data is changed continuously according to a reproduction speed. Band designing of the data slicing circuit is individually performed and can be easily separated from a PLL circuit 18.

Granted: 2000-05-01
Abstract: Self-describing information is included within a device and contains information relating to a graphical representation of the device, the controls available on the device and the interface required to access those controls. The self-describing information is preferably embedded within a ROM within the device and is read by other devices coupled to the device for presenting a graphical user interface through which the device can be remotely controlled by a user. The self-describing information can also include an address from which additional information about the device and upgrades are automatically obtained. This address is either an internet address or points to a location within a network of devices. The address can also be modifiable. Alternatively, the self-describing information also includes driving software for enhancing the graphical user interface and controlling the operation of the device through another system. This driving software is written either in the native language of the deivce on which it is uploaded and executed or in a platform neutral language such as Java<TM>. The graphical user interface is presented on a television, computer or other appropriate system for controlling multiple devices through the system. The controlling system obtains the self-describing information from each device within the configuration. The graphical user interface includes a graphical representation of the devices and specific control features available to the user presented in a graphical orientation. Alternatively, a three-dimensional representation of the device is presented with controls represented on the device. If no controlling system is available, a graphical user interface is controlled by an application within the device and presented on an available display.

Abstract: A method and an apparatus for reducing the optical path of rear image projection systems are provided. A functional mirror is placed between a rear projection screen and a second mirror. Light is projected onto the functional mirror at an angle of incidence that is greater than a critical angle of the functional mirror. This results in the light being reflected from the second mirror back to the functional mirror so as to strike the functional mirror an angle of incidence that is less than the critical angle of the functional mirror; this results in the light passing through the functional mirror. The light passed through the functional mirror is incident on a rear projection screen.
