Abstract: The aim of the invention is to limit the number of possible phase ambiguity resolutions when taking measurements by means of satellite-aided positioning systems. Said aim is achieved by a method which allows the search sector to be better restricted. To this avail, information about the geometry of an antenna array is used for establishing restrictions for said antenna array. Said restrictions allow the search sector and thus the number of acceptable resolutions to be successively reduced. A restriction comprises the utilization of the connecting line between two antennas (A0, A1) that define a primary base line (S01). An additional, secondary base line (S0x) can be calculated by inventively parameterizing the degree of rotational freedom of said secondary base line (S0x) about the primary base line (S01) such that the process is accelerated.

Abstract: The invention provides a bi-directional programming method/system/computer product for a programmer to enter source level instructions via either a visual language interface or a traditional syntactic level (code) interface. Irrespective of which means is used to describe the program, a corresponding “view” of the program (visual or syntax) is generated. Changes to the program can be made at either level, allowing the regeneration of the corresponding view (visual or syntax) to reflect the changes. For example, should the original program be described in a visual format, then a program can be generated in the corresponding syntax level format. Similarly, if a programmer wishes to make changes to this syntax level, then the equivalent version of the program can be regenerated in the visual format to reflect the changes. The invention can advantageously be used to develop back-end logic for an application program.

Abstract: An electric toothbrush includes a brush head that has a plurality of tooth engaging elements, such as bristles and polishers optionally arranged in alternating rows on the brush head. The brush head is driven by an elongate drive shaft connected to drive means typically located in the handle or body portion of the toothbrush. The driveable toothbrush attachment and the handle or body portion are separate modular units. The brush head is operable to slowly rotate (at say, between 60 and 240 rpm), about an axis substantially corresponding to the longitudinal axis of the drive shaft.

Abstract: The present invention provides modified Cdc14 phosphatase proteins, and novel constructs for expression thereof, in which the sequence C-terminal to the catalytic domain has been deleted. This modification results in the expression of a single form of the enzyme, enabling purification of a homogeneous preparation of active enzyme at a high yield.

Abstract: Briefly described, compositions, materials including the compositions, methods of using the compositions, and methods ods of degrading contaminants, are described herein. The composition can include a polyoxometalate/cationic silica material. In addition, the compositions can be made of a polyoxometalate/cationic silica material, a copper (E) salt having a weakly bound anion, and a nitrate salts. Further, the compositions can be made of a polyoxometalate/cationic silica material, a copper (II) salt having a weakly bound anion, a compound selected from tetraethylammonium (TEA) nitrate, tetra-n-butylammonium (TBA) nitrate, and combinations thereof.

Abstract: A method for improving intracellular administration of a therapeutic agent is provided comprising: contacting cells with a compound comprising a charged derivative of a therapeutic agent having a therapeutic activity, the charged derivative being conjugated to a protein having a biological activity of being transported across a cell membrane into a cell; and having the cell transport the compound into the cell where the cell metabolizes at least a portion of the compound to form a charged metabolite product that possesses the therapeutic activity of the therapeutic agent, the charged metabolite product being less prone to being transported across the cell membrane out of the cell relative to the compound and less prone to being transported across the cell membrane out of the cell relative to the therapeutic agent.

Abstract: An external combustion thermodynamic system includes a compression stage for substantially adiabatically compressing a working medium to raise the temperature of the medium and an expansion stage for substantially adiabatically expanding the medium to decrease the temperature of the medium. A first heat exchanger is coupled to the compression stage and the expansion stage to allow the expanded medium to pass therebetween and is structured to transfer heat substantially isochoricly (i.e., at constant volume) between the cold reservoir and the expanded medium. A second heat exchanger is coupled to the compression stage and the expansion stage to allow the compressed medium to pass therebetween. The second heat exchanger is structured to transfer heat substantially isochoricly between the compressed medium and the hot reservoir.

Abstract: A method and apparatus simplify the construction of a concrete panel to include openings through which rebar and concrete slurry extend in order to anchor the panel in a trench at a construction site to form a wall. The method and apparatus of the invention also reduce the likelihood that the panel will settle and damage the panel.
