Abstract: A flexible sensor configured for use in a bladder is flexible and moveable from a first position in which it is configured to not be discharged from the bladder to a second position in which it is configured to be inserted into the bladder. A sensor insertion tool includes an over sheath, a push rod configured to be inserted into a first lumen of the over sheath. The flexible sensor is positioned in the first lumen of the over sheath, the push rod is then inserted partially into the over sheath behind the flexible sensor. The sensor insertion tool is then positioned at a location, such as the opening to the bladder, in which the sensor is to be deployed.

Abstract: A noise abatement system for dental procedures conceived to protect the hearing of dental staff members composed of office managers, dental operators including at least one of dentist, dental hygienist, dental assistant, dental technician and any other dental staff member in the dental operatory, and of patients, comprises a pair of headphones composed of one left and one right phones [1] connected to each other via a flexible strap [2], an audio signal processor (ASP) [7] with a receiver [17] and an on/off talk button [13] with a transmitter and circuitry [21]. Dental operators and patients can toggle an operator/patient switch [8] in a water- and dust-resistant casing of the pair of headphones to switch between operator mode and patient mode.

Abstract: A noise abatement system for dental procedures conceived to protect the hearing of dental operators (dentists, dental hygienists, dental assistants dental technicians and/or any other dental staff member in the dental operatory) as well as of patients, comprises a pair of headphones composed of one (1) left and one (1) right phone [1] connected to each other via a strap [2], an audio signal processor (ASP) [7] with associated circuitry, a remote operator on/off talk button [14] and a voltage source charging station [2530]. The user of the system can toggle an operator/patient switch [8] in the casing of the headphones to switch between operator mode and patient mode. In operator mode, high-frequency noise from dental tools is captured by one (1) left and one (1) right microphone [3], is filtered out by a noise-abating filter [16], as a part of the ASP, and only frequencies from speech signals are allowed to the operator through a pair of speakers [4] mounted in the casing of the phones.
