Abstract

Embodiments of a system including a remotely controlled reaction device and associated controller are described. Methods of use and control of the device are also disclosed. According to various embodiments, a reaction device is placed in an environment in order to perform a chemical reaction in an environment. Exemplary environments include a body of an organism, a body of water, or an enclosed volume of a fluid. In selected embodiments, an acoustic control signal may be used.

Claims

48. A method of controlling a reaction device, comprising:

generating an electrical driving signal; and

driving an acoustic signal generator with the electrical driving signal in a remote controller positioned at a location remote from a reaction device in an environment to produce an acoustic control signal, the reaction device including a remotely activatable control element, and the acoustic control signal sufficient to produce activation of the remotely activatable control element to produce a desired rate of a chemical reaction in the reaction device.

49. The method of claim 48, including generating the electrical driving signal from a model-based calculation.

50. The method of claim 48, including generating the electrical driving signal based on a stored pattern.

51. The method of claim 48, including:

receiving a feedback signal from the environment; and

based upon the feedback signal, generating an acoustic control signal having signal characteristics expected to produce a desired feedback signal.

52. The method of claim 51, wherein receiving a feedback signal from the environment includes receiving a measure of osmolality or pH within at least a portion of the environment.

53. The method of claim 51, wherein receiving a feedback signal from the environment includes receiving a measure of temperature or pressure within at least a portion of the environment.

54. The method of claim 51, wherein receiving a feedback signal from the environment includes receiving a measure of the concentration or activity of a chemical within at least a portion of the environment.

55. The method of claim 48, including:

receiving a feedback signal from the reaction device; and

based upon the feedback signal, generating an acoustic control signal having signal characteristics expected to produce a desired feedback signal.

56. The method of claim 55, wherein receiving a feedback signal from the reaction device includes receiving a signal representing a concentration of a reactant at the reaction region of the reaction device.

57. The method of claim 48, including:

receiving user input of one or more control parameters; and

based upon the one or more control parameters, generating an acoustic control signal having signal characteristics expected to produce a desired rate of reaction in the reaction device.

58. The method of claim 48, including activating the remotely activatable control element to produce heating or cooling of the remotely activatable control element sufficient to modify the chemical reaction occurring at the reaction region.

59. The method of claim 48, including activating the remotely activatable control element to produce a change in configuration of the remotely activatable control element sufficient to modify the chemical reaction occurring at the reaction region.

60. The method of claim 59, wherein the change in configuration includes expansion of the remotely activatable control element.

61. The method of claim 59, wherein the change in configuration includes a change in shape, volume, surface area or orientation of the remotely activatable control element.

62. The method of claim 48, wherein the step of generating an electrical driving signal is performed according to instructions provided in the form of software, hardware or firmware.
