A portable easel comprises an easelback and palette box joined by two lockable hinges mounted on opposing sides, the hinges having friction washers, and having knobs extending outward from shafts of each hinge, the shafts defining a rotational axis. With knobs loosened, the easelback may be rotated to a desired angle relative to the palette box, and, with knobs tightened, the friction washers lock the easelback into position. The easelback further comprises a canvas-holder having a vertically adjustable slidable lower support plate and a vertically extendable shaft, said shaft having a horizontal cross member configured with rotatable hooks for securing a canvas. The palette box further comprises a right-angle baseplate for tripod connection to advantageously place the opened easel's center of gravity at the baseplate-to-tripod connection. The easelback may comprise slots for storing canvases, and the palette box may be configured with multiple compartments for storing paints and accessories.

A semiconductor system and method for repairing failures of a packaged integrated circuit system are provided. The method includes detecting a failure associated with a packaged integrated circuit system after the packaged integrated circuit system is packaged, and repairing the failure by activating a redundancy circuit in the packaged integrated circuit system and deactivating a defective circuit associated with the failure. The process for repairing the failure includes applying a repair voltage to a polysilicon fuse to change a conductivity state of the polysilicon fuse from a first state to a second state. In another embodiment, the polysilicon fuse is replaced by a metal fuse, an anti-fuse, or a non-volatile random access memory.

The present invention is a novel method and computer program product which utilizes an interface capacitor formed by the metal of the probe tip, a dielectric layer, such as an oxide, formed by a contaminant on a solder bump and the metal of the solder bump. The interface capacitor forms a capacitive divider with the inherent capacitances of the automatic test equipment and the device under test (DUT). The voltage characteristics of the capacitive divider are used to drive voltage signals across the interface capacitor to test the DUT. In either direction (i. e. from the automatic test equipment to the DUT or vice versa), by altering the voltage output high amplitude of the driver and/or the voltage input high amplitude of the load, the DUT is validly tested through the interface capacitor. Thus, even if all I/O bumps have an oxide layer, the device may still be validly tested.

Delay associated with each of two signals along respective transmission paths is accurately measured using a delay measurement circuit that is fabricated in situ on the actual device where the circuitry for propagating the two signals is fabricated. Thus, the measured delay associated with each of the two signals is subject to the same fabrication-dependent attributes that affect the actual circuitry through which the two signals will be propagated during operation of the device. The skew between the two signals is quantified as the difference in the measured delays. Coarse and fine delay modules are defined within the transmission path of each of the two signals. Based on the measured skew between the two signals, the coarse and fine delay modules are appropriately set to compensate for the skew. The appropriately settings for the coarse and fine delay modules can be stored in non-volatile memory elements.

Illustrative embodiments of the present invention are directed to methods and computer systems for reporting unusual or anomalous usage or spending of a commodity by consumers. A computer system retrieves a set of usage-information datasets corresponding to a set of consumers, each dataset including past usage of the commodity during at least one of a completed billing period and a current usage of the commodity during the current billing period. The computer system establishes a set of report-trigger conditions for the current billing period, each of the report-trigger conditions corresponding to a consumer. The computer system monitor usage or spending of the set of consumers to determine, for each consumer, whether an estimated usage established for each consumer fulfills the consumer's report-trigger condition. Once the report-trigger condition is fulfilled, the computer system outputs a report to the consumer.
