Appl. No.:

09/840497

Thomas Stone - Beacon Falls CT, US

Assignee:

GoldPocket Interactive, Inc. - Los Angeles CA

International Classification:

H04N 7/10
H04N 7/16

US Classification:

725 32, 725136

Abstract:

A method and apparatus for delivering interactive television (ITV) data by using the same TV scan line that also carries closed caption data. The ITV data is inserted into the scan line with CC data by detecting a gap associated with a first CC data unit. If the gap is large enough to contain all of the group of ITV data units then electronically insert the entire group of ITV data units into the gap. If the gap is not large enough to contain the entire group of ITV data units, insert a subset of the entire group of the ITV data units into the gap and continue to the gaps associated with successive CC data units, inserting subsets of the ITV data into subsequent gaps until the entire ITV message has been inserted into the gaps between CC data units.

Abstract:

A digitizer tablet with a cordless transducer which is capable of providing to the tablet information relating not only to the position of the pointing device but also with respect to the status of any button switches on the transducer. This is obtained by providing a plurality of oscillators, connected in circuits in which the relative ratio of the signal frequency outputs of the oscillators can be varied in response to activation of a switch while at the same time the sum of the amplitudes of the oscillating signals remain constant. Thus, the determination of the sum can be used as a indication of the position of the pointing device with respect to the tablet, whereas by determining the differences in the signal intensities of the different frequency oscillating signals, it is possible to determine the status of the button switches on the pointing device. The invention is typically used with a stylus or cursor driven tablet.

Abstract:

The present invention provides novel test cartridges for use in the assay of liquid samples and methods of carrying out such assays. These test cartridges are particularly useful in assays which include at least one step during which the sample to be assayed and one or more components of the assay system are kept separated by a pierceable member. The test cartridges comprise a housing through which the sample flows during the assay. The housing includes a holding chamber for holding the sample and a test chamber separated by a pierceable member having a cut therein. The test chamber further includes a partition member which has an opening therethrough and includes at least one reagent for the assay. A transfer member movably mounted in the test chamber can move towards and pierce the pierceable member by moving through the cut and contact the liquid sample in the holding chamber. When the transfer member has been moved towards and pierces the pierceable member to contact the liquid sample and a negative pressure is created in the test chamber, liquid sample moves through the transfer member, into the test chamber and through the opening in the partition member.
