A pressure shock wave apparatus applies shock waves to separate substances, such as oil, from a water mixture in an enclosure. The substance, such as oil, is moved toward a substance removal conduit and the water moved toward a water conduit from action of the shock wave apparatus.

Shock waves for oil separation

A battery of shock waves applicators positioned on a support beam having an elliptical or spherical shape in a common device wherein focused shock waves from the applicators combine to provide pseudo-planar waves over a far field distance.

Shock wave device with far field focused reflectors

A system for individualized treatment of a tissue condition with acoustic pressure shocks includes personalized determination and automatic adjustment of a shock wave treatment regimen or shock wave dosage to be administered for personalized treatment based on factors such as a patient's comorbidities, state of the tissue condition, individual physical characteristics and lifestyle parameters.

Acoustic pressure shock waves used for personalized medical treatment of tissue conditions

A product programming system includes a product subject to maintenance, part refurbishment and/or part replacement that has a security device communicatively coupled to a computing device programmed to re-authorize normal operation of the product when a predetermined number of uses has been reached or a predetermined period of time has lapsed.

Distributor product programming system

A method for cleaning pipes using shock wave generating devices (i) within an interior of a pipe and focusing shock waves therein to remove accumulated material and (ii) from the exterior of a pipe by sending shock waves into the pipe from the exterior to remove accumulated material therein.

Shock waves for pipe cleaning

A cleaning or grooming system that uses acoustic pressure shock waves can remove barnacles, algae, biofilms and other undesired materials from the hulls of ships, propellers, rudders, inlet ports for cooling of nuclear submarines, outlet ports, sonar housings, protective grills and other structures that are submerged in salt or fresh water environments.

Cleaning and grooming water submerged structures using acoustic pressure shock waves

Medical devices utilizing shock waves with spark gap electrodes that include fluid holes into the respective electrode cores.

Shock wave electrodes with fluid holes

Medical devices with novel spark gap electrode designs, able to control manually or automatically the electrodes gap are provided. These devices are used to generate a shock wave created by the rapid expansion and collapse of a plasma bubble that is formed between two spark gap electrodes placed in a special liquid medium, when a high differential voltage (kV) is applied to the electrodes. The resulting shock wave impacts a reflector to direct the energy into the body of an animal or a human toward the desired treatment location. This electro-hydraulic principle to create acoustic shock waves as a method of treatment is in use in the medical (lithotripsy, orthopedic use, wound treatment, burns, post-operative treatment, pain treatment, diagnosis, skin and organ transplantation supporting devices, arteriosclerosis treatment), cosmetic (treatment of scars and cellulite) and veterinary (treatment of musculoskeletal disorders) fields.

Increase electrode life in devices used for extracorporeal shockwave therapy (ESWT)

Several methods and devices are provided herein to generate shock waves that are used in the oil industry for well drilling, hydrocarbon or gas exploitation, fracking process or improved oil recovery (IOR), enhanced oil recovery (EOR), cleaning of process waters, oil spills byproducts and oil pipes, which can be used as independent systems or as auxiliary systems concomitantly with other existing technologies. The different devices consist of generating shock waves utilizing either one or more laser sources, or a self-generated combustible gas supply, or a micro-explosive pellet, or piezocrystals, or a piezofiber composite structure.

Apparatuses and methods for generating shock waves for use in the energy industry

A breathing circuit includes inspiratory and expiratory limbs, each having a respective electrically energizable heating circuit. The heating circuits are independently and selectively electrically energized through separate power circuits such as to control the temperature in each limb in a desired fashion so as to reduce rainout in the breathing circuit and particularly in the expiratory limb.

Rainout reduction in a breathing circuit

A heated breathing circuit detection system verifies the proper set up and connection of a breathing circuit to a heater unit of a humidification system. The detection system automatically detects that the breathing circuit is connected to the heater unit, and the nature of the heating circuit(s) thereof. In one embodiment, the resistance of the heating circuit(s) is determined and compared to an expected resistance or range of acceptable resistances to determine if the heater circuit(s) is properly or actually attached and properly operating. The humidification system also has the ability to determine the delivery mode of the breathing circuit, i.e., whether a single inspiratory limb, or both inspiratory and expiratory limbs, is connected to the heater unit.

Heated breathing circuit detection

A heater system is provided for a respiratory system having a PID feedback control in which the coefficients are adjusted, such as in a warm-up process, to correspond to a likely flow rate of gas through a chamber of heated water based on the difference between heat input and heat output in relation to a temperature set point without the need to directly monitor flow rate or humidity level. A steady-state adjustment of the coefficients based on the behavior of the measured temperature in relation to the set point is also disclosed.
