International Classification:

G06Q 10/08
G06N 20/00

Abstract:

A network computer system determines a category of at least a first item of the order request, where the category is determined programmatically by the network computer system based at least in part on a description of the first item. The network computer system further determines one or more delivery parameters for the order request based on the determined category of at least the first item. Based at least in part on the one or more delivery parameters for the order request, the network computer system implements a delivery process that includes selecting a service provider that delivers the one or more items of the order request to the delivery location.

G01S 7/486
H01S 5/183

Abstract:

A characterization circuit for an optical device includes: an optical device, a switch, a switch driver, one or more resistors, and one or more capacitors. The switch driver is configured to receive a trigger pulse from an external pulse generator and to provide the trigger pulse to the switch, which causes the switch to be in an on state. The one or more capacitors are configured to, when the switch is in an off state, receive a charge current (e.g., with a greater than 50 nanoseconds rise time) from an external driver voltage source via the one or more resistors; and, when the switch is in the on state, discharge a current pulse (e.g., with a less than 10 nanosecond pulse width) to the optical device. The optical device is configured to receive the current pulse and to emit, based on the current pulse, an optical output pulse.

A61K 9/50

Abstract:

A pharmaceutically acceptable oral dosage form for delivery of an agent to an intestinal site has one or more active agent regions having an active agent to be delivered to the intestinal site, one or more drying agent regions having at least one drying agent therein capable of drying an area about the intestinal site, the one or more drying agent regions being separate from the one or more active agent regions, and a protective coating at least partially covering a surface of the form. The dosage form has a fluid uptake capacity as measured for the entire dosage form when immersed in a fluid media according to a Dosage Form Fluid Uptake Assay of at least about 20 g fluid per dosage form.
