Abstract: The invention provides a method for detecting one or more analytes, the method comprising: providing a substrate comprising a semiconductor with a porous surface, wherein the porous surface is coated with a fluorocarbon polymeric coating; contacting the porous surface with a fluid or object so that the one or more analytes are retained on the substrate when present in the fluid or on the object; and analysing the substrate by mass spectrometry to detect the one or more analytes if present on the substrate.

Abstract: A heartbeat sensor device for visually indicating a pulse includes a housing attached to an adhesive band. A photoplethysmograph sensor is positioned within the housing and is electronically coupled to a central processing unit. The photoplethysmograph sensor measures the pulse. The central processing unit controls a pulse indication light, causing the pulse indication light to illuminate synchronously with the pulse measured by the photoplethysmograph sensor. The adhesive band sticks the heartbeat sensor device to the skin, for example over the carotid artery, where the photoplethysmograph sensor can detect light absorption changes in the skin caused by the pulse. Alternatively, the heartbeat sensor device may include a transducer connection port configured to receive a transducer cable. The transducer cable enables communication between the central processing unit and a display screen. In such embodiments, the display screen provides the visual pulse indicators.

Abstract: A visor system for a protective sport helmet (e.g., a hockey helmet) wearable on a head of a user (e.g., a hockey player) is provided. The visor system comprises a visor for protecting at least part of a face of the user. The visor is transparent and comprises left and right connectors. The visor system also comprises left and right visor supports for supporting the visor on left and right sides of the protective sport helmet. The left and right connectors of the visor are toollessly connectable to and toollessly disconnectable from the left and right visor supports to allow the user to toollessly connect the visor to the left and right visor supports and toollessly disconnect the visor from the left and right visor supports. The visor system may be configured to define an open gap from a top edge of the visor to the outer shell when the left and right visor supports are supporting the visor on the left and right sides of the protective sport helmet.

Abstract: The present invention provides a ladder cover made up of fabric which prevents the marring of the wall from the top edges of the ladder, is enabled to couple to any ladder type and consists of a loop which secures construction tools to the ladder cover.
