Abstract: A filter is provided within a transparent drinking straw. The filter has a dense core region and a less dense outer peripherial region. The filter is retained in place within the straw by frictional forces under static conditions. The frictional forces which maintain the filter in place under static conditions may be overcome by fluid flowing through the straw causing the filter to move within the conduit. The filter may support particulate matter which may be a medication or drug. Accordingly, the device may be used as delivery device for drugs administered by oral ingestion. Movement of the filter from a first to a second position provides a visual indication that a predetemined volume of fluid has passed through the conduit.

Abstract: A putting practice device for practicing the velocity of a putt which has a ramp section and two trough sections. A ball having a predetermined speed will travel up the ramp and fall into the first trough section. If the ball has insufficient velocity to climb a ridge which defines the rear of the trough, it will be momentarily retained in the first trough section and fed to a lateral side of the device. Balls traveling with greater velocity may pass over the ridge and enter a second trough area where they will be momentarily retained and fed to a lateral side of the device.

Abstract: An accurate, yet ultra low power fuse electronics is presented in which two methods are used to reduce power consumption in the fuze electronics. First, the fuze uses low power 3.3 volt logic chips ("LV" series or equivalent CMOS logic chips) along with switches that have low input capacitance and low quiescent current. Second, a circuit design is used which, while still accomplishing the objects of the invention, drastically reduces the number of electronic elements required. When a projectile is fired from a weapon, a fire control system transmits a signal to a data conditioner located on the projectile. The data conditioner demodulates and filters the signal, producing a burst time data word which is transmitted to a microcontroller. The data conditioner is comprised of passive components, therefore no supply power is required. The microcontroller decodes the data word and also uses the data word to correct any error in the high and low speed fuze oscillators.

Abstract: An improved method and architecture for mapping data between fixed structure datasets defined by different computer formats. The method employs a simple intuitive mapping template which operates from an embedded knowledge of the structure rules for the data being exchanged. The mapping template is flexible and allows the details of the data manipulation required for translation to be expressed by a layperson, and without the requirement that they define the entire message structure in every detail. It is also possible for the mapping template(s) themselves to be transmitted along with the datasets to facilitate conversion between data formats.
Abstract: A method and apparatus for firing a firearm. A trigger is pulled which causes a hammer to rotate away from an electrical power source. After the hammer passes its maximum position, it is released by the trigger releases it, thereby causing the hammer to strike the electrical power source. The force from the hammer causes electrical energy to flow from the electrical power source to an electrically activated primer, thereby igniting the primer.
Abstract: A system for testing a data transmission link between first and second terminal devices such as modems. The first terminal device transmits a test data sequence which it is received at an output access (20) of the second terminal device. That device also has an input access (21), first and second clocks which set the timing of data at the input and output accesses, and a loop-back circuit for connecting the output access to the input access to retransmit a received test sequence back to the first terminal device. Since different modems often operate at different data rates, the input and output clock rates may differ. However, during loop-back operation the clocks must be synchronized in order to avoid loss of data.
Abstract: This invention relates to a geogrid structure which is comprised of two or more layers of rigidly bonded flexible mesh structures. The mesh openings of each layer, without superimposing, overlay mesh openings of other layers, resulting in a geogrid structure which consists of small and large sized mesh openings. The smaller sized mesh openings are designed to reduce vertical migration of the smaller aggregate particles into the subgrade and to reduce pumping of the subgrade material into the aggregate layer. The rigid bonding of multiple layers of mesh structure provides a mechanism for transmission of tensile stress which is less dependent upon interlocking of aggregate particles. Furthermore, by bonding multiple layers of mesh structure, the number of tensile elements per unit area is increased, and as a result, the interaction of the geogrid with the fill material is enhanced.
