Abstract: The roof scupper overflow with sensor cooperatively engages and replaces a conventional roof opening through a wall or in a corner to prevent trash from reaching and clogging the conventional roof basket and drain. Accumulating trash builds up on the screen of the roof scupper overflow causing a foam float or buoy connected to a trash tray to rise permitting water to run under the trash trap at roof level. The trash tray is retained to a base with magnets. When the water reaches a predetermined level, the foam buoy rises pulling the trash tray away from the base allowing water to flow to the conventional roof drain basket and activating a magnet switch sending a signal to overflow sensor and a control module connected to WIFI service.

Abstract: The present specification describes a method for determining the distance of an object from the tip of an endoscope during an endoscopic procedure, wherein at least one lens is configured to converge light from outside the tip onto a sensor that includes a plurality of photodiodes a portion of which are adjacent pairs of photodiodes configured to be phase detection pixels. The method includes receiving light into each adjacent pair of photodiodes, wherein said light is reflected off a surface of said object; determining a first response curve to said light for a first photodiode of said adjacent pair of photodiodes and a second response curve to said light for a second photodiode of said adjacent pair of photodiodes; identifying an intersection between the first response curve and the second response curve; and using data derived from said intersection to determine said distance to the object.

Abstract: The roof drain overflow cover with sensor cooperatively engages and covers a conventional roof drain cap cover to prevent trash from reaching and clogging the conventional roof basket cover and drain. Accumulating trash builds up on the screen of the overflow prevention device causing a doughnut shaped buoy connected to a trash tray to rise. The trash tray is retained to a base with magnets. When the water reaches a predetermined level, the doughnut shaped buoy rises pulling the trash tray away from the base allowing water to flow to the conventional roof drain basket and activating an overflow sensor and a control module. The control module is in communication with the water flow sensor and includes an indicator which is activated when the water flow sensor detects the detachment of the trash tray from the base indicating a potential flooding situation with the roof drainage system.

In particular, methods of purifying such recombinant antibody molecules are provided wherein imidazole or an imidazole-analogue is added during the elution of the recombinant antibody molecule from an affinity chromatography resin, such as a protein-A-based resin.

Abstract: The travel mug includes a vessel with a removable, angled partition and an engageable flow restrictor. The partition separates the vessel into a fluid reservoir chamber and a fluid dispensing chamber. The fluid dispensing chamber has a direct fluid flow path out of the upper, open end of the vessel. The fluid reservoir chamber has an indirect flow path out of the upper, open end of the vessel through the fluid dispensing chamber. An engageable flow restrictor is configured to control fluid flow along the indirect fluid flow path at the partition. The flow restrictor is disengaged when the travel mug is upright and at rest and engaged when the travel mug is positioned for dispensing.
