Systems and methods to deliver goods to a buyer that is dynamically located are described. The system communicates a user interface to a device that is identified as being located at a first location and associated with a customer. The user interface includes items that are identified as being located within a predetermined distance from the device. The system receives an order from the device that authorizes the purchase of an item and delivery of the item to the customer. The system automatically selects a courier from a plurality of couriers that are identified as being located at different locations. The system communicates a user interface to a courier mobile device that includes instructions to enable the courier to retrieve the item from a second location and deliver the item to the first location.

The present invention is directed to novel 3-(3,5-disubstituted-4-hydroxyphenyl)-propionamide derivatives that are inhibitors of Cathepsin B. Pharmaceutical composition comprising these compounds, method of treating diseases mediated by Cathepsin B, utilizing these compounds and methods of preparing these compounds are also disclosed.
摘要:
A method of treating a molybdenum (moly) mask used in a C4 process to pattern C4 contacts. The moly mask has a wafer side which contacts a wafer during the C4 process and has a rough surface that includes spikes/projections of moly. The moly mask also has a non wafer side and a plurality of holes extending through the mask to pattern C4 contacts in the C4 process. An adhesive layer, such as an adhesive tape, is applied to the non wafer side of the moly mask, to enable a polishing tool to pull a vacuum on the non wafer side of the moly mask in spite of the presence of the holes to secure the moly mask during a subsequent polishing step. The tape also functions as a cushion so that defects on the non wafer side of the moly mask do not replicate through the moly mask to the polished wafer side of the moly mask. The wafer side of the moly mask is then subjected to mechanical or chemical/mechanical polishing to substantially remove the spikes of moly without significantly altering the dimensions of the moly mask or the holes.
摘要:
The present invention is a method for injection and stacking of analytes in high salt samples. This stacking method works with both pressure injection or electrokinetic injection. The ability to stack analytes with electrokinetic injection allows the translation of high-salt stacking from the capillary to the microchip format.
摘要:
A method of partially scrambling a data stream (6) including transport stream packets (7), each transport stream packet (7) having a header (8) and a payload (9), wherein a sequence of transport stream packets (7) has payloads carrying encoded data elements, arranged in units (15), includes: selecting transport stream packets (7) forming a subsequence of the sequence, and scrambling at least part of the payloads (9) of each transport stream packet (7) in the subsequence. The method further includes monitoring the payloads (9) of at least some of the transport stream packets (7) in the sequence for the presence of data (22) indicating a boundary between two subsequent units (15), and, for selected units (15), including at least one of the transport stream packets (7) carrying data forming part of the selected unit (15) in the sub-sequence.
摘要:
A flying toy having a first and a second guideline support, each guideline having two ends and a handle member respectively secured at each end. A body member for operating aerodynamically may include a frame and sail, or alternatively, the frame and sail may be replaced by a one-piece or composite sail frameless structure. In an alternative embodiment, a single guideline replaces the two guidelines. Support elements are slideably secured to the body member and to the fasteners for supporting the body in a desired orientation between the first and second guidelines. Alternatively, the support elements may be included as a part of the frame of the body member or some embodiments eliminated.
摘要:
A toy having a first and a second guide line support, each guide line having two ends and a handle member respectively secured at each end. A body member for operating aerodynamically includes a frame, a sail, and spaced fasteners which are also secured to the first and to the second guide lines. In one embodiment support elements are slideably secured to the body member and to the fasteners for supporting the body in a desired orientation between the first and second guidelines. Alternatively, the support members may be included as a part of the frame of the body member.
