Abstract: A method and system is disclosed for evaluating a chat message sent between users of an online environment. The method may include receiving a chat message and parsing the message into words. The method determines the acceptability of the message by matching the message to a plurality of acceptable messages stored in a data structure.

The method may use templates to determine if the message has acceptable word combinations based on the metadata. The method may also compare the metadata to rules wherein the rules determine if the message has unacceptable word combinations based on the metadata. The method may send the message to a user upon determining words in the message do not match any word in a list of unacceptable words.

Abstract: A seat lift for a bath that includes a seat, a seat back hingedly connected to the seat, a torsion spring, and a guide means for guiding the seat in reversible movement between lower and upper positions. The guide means is configured so that movement between the lower and upper positions comprises both vertical and lateral movement of the seat relative to a base of the bath. The seat back may move between a first seat back position in which the seat back is substantially upright and a second seat back position in which the seat back is orientated so that a user is leaning backwards. The torsion spring biases the seat back to rotate around the hinge connecting the seat back to the seat toward the first seat back position. The torsion spring torque is smaller when the seat is in the lower position than in the upper position.

Abstract: An embodiment of a reagent container includes a bottle with a pipe to reduce the effects of reagent sloshing. The bottle has an elongated base and an opposed cover connected by side walls and an end wall. A flat platform surrounded by a raised rim lies in the base opposite an opening in the cover. A ribbed pipe frictionally fits within the bottle opening and may attach to the anchor region leaving vent passages around the pipe. The pipe includes an aperture adjacent to the anchor region and oriented toward the end wall so that sloshed fluid has only a small effect on the level of reagent in the pipe during transfers. A modified blow molding process produces the anchor region by extending a pin a predetermined distance into a mold while the molded material is still plastic.
