A commodity trust is provided by a Trustee for a particular commodity. Commodity shares are backed by the Trustee's custody of the actual commodity. For example, commodity shares are created and issued when a trust participant deposits an amount of the commodity with the Trustee or a custodian acting on behalf of the Trustee. After confirmation of the receipt of the commodity, an amount of commodity shares is issued by the Trustee, which is equal in value to the value of the commodity.

A method and apparatus are disclosed for providing negative pressure at a wound site. The apparatus includes a negative pressure reservoir and a reservoir valve for selectively connecting the reservoir to a wound chamber at a wound site.

A comprehensive, convenient, cost-effective, and intuitive mechanism for individuals to create, manage, and modify customized portfolios of assets and liabilities based on the individual's investment preferences, weighting schemes, risk tolerance, and timeframe. The mechanism includes a server (64) that has data storage (66) for the individual's data. The individual input (60) is used in asset and liability selections (62). There are investment tools (62) to educate individuals on investing concepts, terms, definitions, and strategies. Individuals, through an on-line discussion group, can discuss their investing questions with knowledgeable investors and access other individuals' investment related issues and comments. Investing can include fractional shares and odd lots. The system associated with the mechanism aggregates and nets the trading orders to reduce transactional costs.

A semiconductor chip assembly includes a semiconductor chip that includes first and second opposing major surfaces, wherein the first surface of the chip includes a conductive pad, a substrate that includes first and second opposing major surfaces, wherein the first and second surfaces of the substrate include a conductive terminal and a dielectric base, the conductive terminal extends through the dielectric base to the first and second surfaces of the substrate, a cavity extends from the first surface of the substrate into the substrate, the first surfaces of the chip and the substrate face in a first direction, the second surfaces of the chip and the substrate face in a second direction, and the chip extends into the cavity, a conductive trace in an electrically conductive path between the conductive terminal and the pad, and an adhesive disposed between the conductive trace and the chip, the conductive trace and the substrate, and the chip and the substrate.

A system and method of recording audio-visual (A/V) contents directly to a variety of portable media players (PMPs). The recorded contents can be played back by the portable media players immediately without further format conversions. To facilitate immediate playback of the recorded contents, the recording apparatus contains an identification device configured to automatically identify types of portable media players connected to an exemplary recording device that stores the A/V contents. Once the type of portable media player is identified, the recording device automatically generates compressed bit stream in a format that is compatible with the portable media player. Depending upon the nature of the input, the recording apparatus digitizes, encodes and/or transcodes the A/V contents and stores directly into the portable media player's local storage in playback ready format.

Processing a wafer using a double side grinder having a pair of grinding wheels. Warp data is obtained by a warp measurement device for measuring warp of a wafer as ground by the double side grinder. The warp data is received and a nanotopography of the wafer is predicted based on the received warp data. A grinding parameter is determined based on the predicted nanotopography of the wafer. Operation of the double side grinder is adjusted based on the determined grinding parameter.

The invention relates to a group of shopping trolleys formed by at least two different shopping trolleys, respectively comprising an undercarriage and a basket carried by the undercarriage. The same shopping trolleys can be parked in rows, in such a way that the baskets and the undercarriages are partially inserted into each other. At least one connecting means is provided beneath the bottom of the basket and outside the lateral walls of the basket, said connecting means comprising connecting points that enable a basket to be fixed to an undercarriage during the course of the assembly process. The different trolleys are differentiated by at least the different width of the baskets or alternatively by the different width of the undercarriages. The arrangement of at least the connecting points corresponding to the basket, or alternatively at least the connecting points corresponding to the undercarriage is the same for all of the shopping trolleys.

A method for remotely monitoring the cardiovascular condition of a patent includes using a data acquisition device at a patient site to non-invasively acquire cardiovascular condition information from a patient. The cardiovascular condition information includes a data stream of pulse pressure-related data. The cardiovascular condition information acquired by the data acquisition device is transmitted to a remote processor capable of performing data processing and data storage functions on the transmitted cardiovascular condition information. The cardiovascular condition information processed by the remote processor is transmitted to a data display device at a healthcare provider site remote from the data acquisition device for permitting the healthcare provider to use the cardiovascular condition information to monitor the cardiovascular condition of the patient.
