Irrigation and drainage systems are disclosed, including a saturated zone and at least one pipe in communication with the saturated zone. The pipe(s) can be configured to comprise a tubarc porous microstructure for conducting water from the saturated zone to an unsaturated zone in order to drain the water from the saturated zone. The water can be delivered from the saturated zone to the unsaturated zone through the tubarc porous microstructure, thereby permitting the water to be harnessed for irrigation or drainage through the hydrodynamic movement of the water from one zone of saturation or unsaturation to another.

The present invention is directed to a system and method for searching and retrieving location information associated with one or more points of interests, whereby the search criteria can be dependent upon the location of a point of interest with respect to the the real-time position of the user, and any preferences or search restrictions selected by the user, such as rating information about the point of interest. Upon selecting a point of interest from the search result, the user is then given further information regarding the selected point of interest, including but not limited to directions for traveling to the point of interest. Additionally, the present invention can provide to the user a proximity notification once the user is within a certain distance from the point interest. Finally, while at a point of interest, the user can provide to the system information regarding the point of interest, such as rating of the food of a restaurant, without having to specifically identify the point of interest as the system can self-identify the point of interest by using the position information of the user.

Classes of liquid aminosilanes have been found which allow for the production of silicon carbo-nitride films of the general formula Si_xC_yN_z. These aminosilanes, in contrast, to some of the precursors employed heretofore, are liquid at room temperature and pressure allowing for convenient handling. In addition, the invention relates to a process for producing such films.

The classes of compounds are generally represented by the formulas:

• • and mixtures thereof, wherein R and R¹ in the formulas represent aliphatic groups typically having from 2 to about 10 carbon atoms, e.g., alkyl, cycloalkyl with R and R¹ in formula A also being combinable into a cyclic group, and R² representing a single bond, (CH₂)_n, a ring, or SiH₂.

A stimulator for stimulating the leg or other parts of the body e.g. the leg in a patient with drop foot is provided, the stimulator being controlled by e.g a foot switch but being reliable in use and therefore commanding acceptance by users. The foot switch has to work in adverse environmental conditions and is subject to repeated use so that its characteristics vary with time. The invention provides a functional electrical stimulator for attachment to the leg that has adaptive characteristics and comprises first and second electrodes for attachment to the leg to apply an electrical stimulus, a foot switch for sensing foot rise or foot strike, a circuit responsive to said foot switch for generating stimulation pulses; and means forming part of said circuit for responding to changes in the resistance characteristics of said switch means by adjusting a corresponding response threshold of said circuit.The invention also provides a two-channel stimulator that offers various possibilities for controlling the signals to be supplied to different muscle groups. For example, means may be provided defining a signal pathway between the first and second channels so that the supply of stimulation pulses in one of said first and second channels can be controlled by the state of switch means associated with the other of said first and second channels. In a further embodiment means defining a signal pathway between the first and second channels is arranged so that the supply of stimulation pulses in one of said first and second channels can be controlled by the state of activity of the other of said first and second channels. In a yet further embodiment the first channel has means arranged to cause the stimulation pulses to time-out after a predetermined period and the second channel having no or disabled timing means so that supply of stimulation pulses is continuous in a predetermined state of limb position responsive switch means associated with that channel. The two-channel stimulator can be used e.g., to treat bilateral dropped foot.

The present invention involves the prescribing and/or dispensing ophthalmic lenses, such as progressive addition lenses, for a wearer. In one form of the invention lens usage information is obtained from a wearer and entered into a programmed computer. The programmed computer processes the lens usage information to provide a separate weighted lifestyle score for each of one or more respective lifestyle score categories, such that each weighted lifestyle score is a function of a predetermined relationship between the respective lifestyle score category and at least ophthalmic lens design feature. The programmed computer then selects or designs an ophthalmic lens design using one or more of the weighted lifestyle scores such that the selected or designed ophthalmic lens has at least one lens design feature which has been customised using one or more of the weighted lifestyle scores.
