Abstract:
The present invention relates to the reprogramming of differentiated somatic cells, such as those differentiated cells that arise from embryonic mesoderm, into glial cells. Glial cells produced from this reprogramming are functionally equivalent to glial cells that arise from ectodermal origins.
Abstract:
The present invention provides methods for generating oligodendrocyte progenitor cells from pluripotent cells, as well as methods for sustaining these oligodendrocyte progenitor cells in relatively pure cultures for long periods of time. The present invention also provides methods for further differentiating these oligodendrocyte progenitor cells into various glial cells.
Abstract:

Abstract:
A method of a portable electronic device providing payment from an electronic wallet is provided. The method comprises prompting for input of a personal identification number (PIN) after the wallet has been opened and providing payment from the wallet after receiving the PIN, when the wallet is configured to a first level of security. The method also comprises providing payment from the wallet after the wallet has been opened, when the wallet is configured to a second level of wallet security, wherein the PIN is not contemporaneously input. The method also comprises providing payment from the wallet when the electronic portable device has been activated, when the wallet is configured to a third level of wallet security, wherein the wallet is not opened and the PIN is not contemporaneously input.

Abstract:
A method and system for delivering location information through a voice messaging system is provided. A mobile subscriber may be directed to a voice messaging system if a party is unavailable or chooses not to accept the call. The mobile subscriber may indicate to the voice messaging system that he would like to have his location information be made available to the party. The voice messaging system may contact a location system to obtain the location of the mobile subscriber based on the location of the mobile subscriber's terminal. The party may retrieve the mobile subscriber's location information from the voice messaging system.

Abstract:
The present invention includes a system and method of electronically executing transactions with a preprogrammed main computer having data and image storage and retrieval equipment. A plurality of electronic images of works of art which are for sale are created by at least one listing dealer and stored on the storage equipment associated with the main computer. Data is input about each stored image and input data is associated with each corresponding stored image. A plurality of preprogrammed intelligent terminals each having data storage and retrieval equipment, at least one display screen and at least one input device, located at at least one listing dealer location and at at least one buying dealer location communicate with the main computer. Search criteria are input through the intelligent terminals for selecting at least one of the stored electronic images for review. Selected images and corresponding data are communicated to the intelligent terminals and at least a portion of the selected electronic images are displayed. A reservation on at least one of the displayed electronic images can be made to prevent the completion of a sale transaction involving the artwork corresponding to the selected reserved electronic image. An indication of the reserve status of the work is displayed in conjunction with the display of the reserved work on any of the intelligent terminals. A buy order can be input on the intelligent terminals to transact a purchase of the artwork corresponding to the electronic image subject to the buy order. Instructions to complete the purchase are automatically generated and communicated to the intelligent terminals corresponding to the appropriate listing dealer and the appropriate buying dealer.
Abstract:
A bit position, M, that determines the accuracy and efficiency of the approximation is selected from an N bit binary number. The multiplicand is generated by removing the Mth bit from the binary number, shifting the bits of lower order than the Mth bit up on position, then filling the lowest order bit with a zero. The multiplier is generated by removing the Mth bit, and all lower order bits from the binary number. Booth's algorithm is then used to multiply the multiplicand and the multiplier except that the Mth bit is used instead of an assumed zero during the first step of the multiplication. In hardware, a partial Booth-encoded multiplier is used to produce and approximate square of a binary number. For an N bit number, and a selected bit in the Mth position, the partial Booth-encoded multiplier has N columns, and N−M rows and N−M booth encoders. The inputs to the columns are wired so that the multiplicand has the Mth bit from the binary number removed and the bits of lower order than the Mth bit up are shifted up position, the lowest order bit being filled with a zero. The inputs to the Booth encoders are the N−M highest order bits of the binary number. The Mth bit of the binary number is input to the first Booth encoder instead of an assumed zero.
Abstract:
A system of encoding a plurality of logic paths. A number of logic paths are subdivided into groups of N, N being greater than one. Each group of N logic paths is encoded such that an assertion of a given combination of the N logic paths results in a predetermined one out of 2.sup.N signal lines being asserted. Simultaneous assertion of more than one of the 2.sup.N signal lines is defined as an invalid state. A simultaneous non-assertion of all of the 2.sup.N signal lines enables precharging of the signal lines for dynamic operation. 1-of-2.sup.N encoding enables transmission of N variables by firing one out of N wires (rather than every wire, as in static logic, or one out of two wires, as in mousetrap logic). Signal degradation due to noise and coupling is reduced. In a multiplexer, 1-of-2.sup.N encoding reduces the load on the multiplexer's shift lines. Several 1-of-2.sup.N encoded multiplexers may be interconnected to form a self-timed dynamic shift register comprising one or more stages of tiered multiplexers. 1-of-2.sup.N encoding enables closer wire routings within such a shift register. Furthermore, 1-of-2.sup.N encoding can reduce the number of multiplexers required to implement a shift function.
