Abstract: The disclosure relates to electronic reader devices, detection compositions and methods for detecting heavy metals (e.g., lead) in water samples using a simple, rapid and highly selective immunoassay system, including lateral and upward flow assay systems. The immunoassay is designed to detect very low levels of a contaminating analyte such as lead at less than 1 ppb with high specificity and selectivity from any common water source (e.g., tap or drinking water). Advantageously, implementation of the assay requires no formal technical training or expensive equipment or reagents and is provided with a multi-use reader that can be used for 50 samples or more. The immunoassay sample collector systems are consumable (single use) and can be purchased in any desired quantity. Assay results are wirelessly transmitted from the reader using a SafeSpout-designed app., which provides important information based on the test results.

Abstract: The invention relates to a shaver, comprising a handle, at least two rotary shaving heads, driven by at least one drive shaft which protrudes from said handle, and a support structure for supporting said shaving heads onto the handle so as to have their joined shaving surface (S) extend substantially perpendicular to said at least one drive shaft. The support structure is configured such, that a space (A), restricted at one side by the shaving heads and at the opposite side by the handle, is substantially open to its remaining, surrounding side.

Abstract: The spray assembly for a droplet spray teeth cleaning system includes a guidance member at the end thereof. The spray assembly includes a nozzle through which a spray of liquid is directed to the teeth for cleaning. The guidance member is configured and mounted relative to the nozzle to provide a selected standoff distance between the nozzle and the teeth and includes a portion which is configured to fit in the interproximal space between adjacent teeth and gums, or against the frontal portions of the teeth, so that the user knows the location of the spray relative to the teeth.

Abstract: The invention relates to a shaver (1), comprising a handle (2), at least two rotary shaving heads (5), driven by at least one drive shaft (15; 115; 215) which protrudes from said handle (2), and a support structure (6) for supporting said shaving heads (5) onto the handle (2) so as to have their joined shaving surface (S) extend substantially perpendicular to said at least one drive shaft (15; 115; 215). The support structure (6) is configured such, that a space (A), restricted at one side by the shaving heads (5) and at the opposite side by the handle (2), is substantially open to its remaining, surrounding side.

The support structure (6) is configured such, that a space (A), restricted at one side by the shaving heads (5) and at the opposite side by the handle (2), is substantially open to its remaining, surrounding side.

Abstract: The spray assembly for a droplet spray teeth cleaning system includes a guidance member (40, 56, 80, 86) at the end thereof. The spray assembly includes a nozzle (24) through which a spray of liquid is directed to the teeth for cleaning. The guidance member is configured and mounted relative to the nozzle to provide a selected standoff distance between the nozzle and the teeth and includes a portion which is configured to fit in the interproximal space between adjacent teeth and gums, or against the frontal portions of the teeth, so that the user knows the location of the spray relative to the teeth.
