     FIELD 
     This disclosure relates generally to control of electrical devices, and more particularly to control of patient-lifting-devices. 
     BACKGROUND 
     People with physical difficulties rely on external means to provide motion. The external means vary from physical assistance of another person, to an animal to lift and transport a person with physical difficulties, to electrically and/or hydraulically actuated lifting devices that physically lift and transport the person with physical difficulties. 
     Conventional control of the electrically and/or hydraulically actuated patient-lifting-devices has included a hand-held keypad controller that includes buttons for up, down, forward, backward and stop movement. The patient-lifting-device is also known as a patient hoist or a lift.

     System Level Overview 
     A system level overview of the operation of an implementation is described in this section of the detailed description. 
       FIG. 1  is a block diagram of an overview of a system  100  to control a patient-lifting-device, according to an implementation. System  100  provides a convenient means to control an electrically-controlled patient-lifting-device. 
     System  100  includes a command interface unit  102  that receives information from a human in any one of a number of different communication methods and transmits command(s)  104  to a processor  106 . Examples of commands  104  include “move up” “move down” “move forward” and “move backward.” One implementation of the command interface unit  102  is described in  FIG. 3  and another implementation of the command interface unit  102  is described in  FIG. 4 . In some implementations of the information that is received by the command interface unit  102 , the information is multisensory audio input which is input from a number of sources, such as a keyboard, a hand-held keypad controller that includes buttons for up, down, forward, backward and stop, a synaptic activity sensor; and including audio input. The multisensory input is described in greater detail in  FIG. 5 . 
     In some implementations, the multisensory audio input includes only input from an audio source and input from a hand-held keypad controller. 
     The processor  106  in system  100  receives the command(s)  104  and generates one or more instruction(s)  108  that are specifically tailored for a lift-device-controller  110  that accomplishes the command. 
     The lift-device-controller  110  receives the instruction(s)  108  and generates one or more electric signal(s)  112  that are specifically tailored for a patient-movement-actuator  114  that accomplish or effectuate the one or more instruction(s)  108 . The lift-device-controller  110  transmits the electrical signal(s)  112  to the patient-movement-actuator  114 . One example of the patient-movement-actuator  114  is the patient-movement-actuator  1400  in  FIG. 14 . When the patient-lifting-device operates in accordance with the electrical signal(s)  112  from the lift-device-controller  110 , the patient-movement-actuator  114  performs the command(s)  104  from the command interface unit  102 . 
     In some implementations, the information that is received by the command interface unit  102  is audio information only. However, in some variations of these implementations, electrical control signals from a hand-held keypad controller are received by the patient-movement-actuator  114 , along with electrical control signals  112  from the lift-device-controller  110  which provides dual, and only dual, multisensory control of the patient-movement-actuator  114  from the hand-held keypad controller and the audio information. 
     System  100  provides command control of the patient-movement-actuator  114  of a patient-lifting-device through a variety of input mediums, such verbal audio input, hand-held keypad controllers synaptic activity sensor. The multisensory command input benefits people with physical difficulties by reducing if not completely eliminating the requirement to manually control the patient-lifting-device. 
     Some implementations of system  100  do not include the instructions  108  and the lift-device-controller  110 , and instead, the processor  106  is directly connected to the patient-movement-actuator  114  and the processor generates the electrical signals  112  that are specifically tailored for the patient-movement-actuator  114  that accomplish or effectuate the command(s)  104 . 
     While the system  100  is not limited to any particular command interface unit  102 , command(s)  104 , processor  106 , instruction(s)  108 , lift-device-controller  110 , electric signal(s)  112 , and patient-movement-actuator  114 , for sake of clarity a simplified command interface unit  102 , command(s)  104 , processor  106 , instruction(s)  108 , lift-device-controller  110 , electric signal(s)  112 , and patient-movement-actuator  114  are described. 
     Apparatus Implementations 
     In the previous section, a system level overview of the operation of an implementation was described. In this section, the particular apparatus of such an implementation are described by reference to a series of diagrams. 
       FIG. 2  is a block diagram of apparatus  200  to control a patient-lifting-device in reference to a patient medical condition, according to an implementation. Apparatus  200  provides a convenient means to control and electrically-controlled patient-lifting-device in reference to patient medical condition. 
     Apparatus  200  includes one or more sensor(s)  202  of patient condition. Examples of the sensor(s)  202  include heart rate sensor temperature sensor and blood pressure sensor. In apparatus  200 , patient sensor data  204  from the patient medical sensor(s)  202  are received by the processor  106 . The instruction(s)  108  that are generated by the processor from the command(s)  104  of the command interface unit  102  are generated in reference to the patient medical data  204 . Thus apparatus  200  generates instruction(s)  108  that ultimately control the patient-lifting-device in any manner that is less detrimental to the patient in consideration of the medical condition of the patient as indicated by the patient medical sensor data  204 . 
     Some implementations of apparatus  200  do not include the instructions  108  and the lift-device-controller  110 , and instead, the processor  106  is directly connected to the patient-movement-actuator  114  and the processor generates the electrical signals  112  that are specifically tailored for the patient-movement-actuator  114  that accomplish or effectuate the command(s)  104 . 
     Apparatus  200  provides command control of a patient-movement-actuator  114  of a patient-lifting-device through a variety of input mediums, such verbal audio input, hand-held keypad controllers synaptic activity sensor in reference or consideration to the medical condition of a patient. The multisensory command input benefits people with physical difficulties by reducing if not completely eliminating the requirement to manually control the patient-lifting-device. 
       FIG. 3  is a block diagram of a command interface unit apparatus  300  that according to an implementation receives information from a human and generates command(s)  104  from the human information, in reference to authority of the human and the state of the mind of the human. Apparatus  300  provides command(s)  104  that are suitable to be processed by a processor in control of a patient-lifting-device that are generated in reference to the authority in the state of mind of the human. Apparatus  300  is one implementation of the command interface unit  102  and  FIG. 1  and  FIG. 2 . 
     The command interface unit  102  shown in  FIG. 3  includes an input device  302  that receives information in any one of a number of different communication methods. One implementation of a number of different input devices  302  is described in  FIG. 5 . Input that is captured as analog data or analog signals is converted to digital data by a conventional analog to digital converter (A/D). 
     The received information is processed in a three-pronged approach. In a first prong, the information is processed by a command interpreter  308 . The command interpreter analyzes the information and extracts a command  310  from the information. Examples of commands  310  include “move up” “move down” “move forward” and “move backward.” In a second prong, the information is processed by a state-of-mind filter  312 . The state-of-mind filter  312  analyzes the information and extracts from the information indicators of the emotional state of the operator, indicators of the competency of the operator, and/or indicators of the state-of-mind of the operator  314 . In a third prong, the information is processed by an authority filter  316 . The authority  FIG. 316  analyzes the information and extracts from the information an indicator  318  of the authority of the operator. 
     An authority engine  312  receives the command  310 , the state-of-mind  314  and the indicator of authority of the operator  318 . The authority engine  320  analyzes the command  310 , the state-of-mind  314  and the indicator of authority of the operator  318  in reference to an authority database  322 . In one implementation the authority engine determines whether or not the command  310  is authorized by the authority of the operator  318 . If the command  310  is not authorized by the authority of the operator  318 , the command  310  is rejected. In another implementation the authority engine  320  determines whether or not the state-of-mind  314  of the operator is of a sufficient level for the command  310 . If the state-of-mind  314  for the operator is not of a sufficient level for the command  310 , command  310  is rejected. 
     If the authority engine  320  determines that both the state-of-mind  314  and the authority  318  of the operator are sufficient for the command  310 , the authority engine generates or designates an authorized command  324  from the command  310 . 
     Command interface unit apparatus  300  provides command control of a patient-movement-actuator  114  of a patient-lifting-device through a variety of input mediums, such verbal audio input, hand-held keypad controllers synaptic activity sensor in reference or consideration to the authority and emotion, competency and state of mind of the operator from which the command is issued. The multisensory command input of command interface unit apparatus  300  benefits people with physical difficulties by reducing if not completely eliminating the requirement to manually control the patient-movement-actuator  114 . 
       FIG. 4  is a block diagram of a command interface unit apparatus  400  that according to an implementation receives information from a human and generates command(s)  104  from the human information, in reference to authority of the human and the state of the mind of the human. Apparatus  400  provides command(s)  104  that are suitable to be processed by a processor in control of a patient-lifting-device that are generated in reference to the authority in the state of mind of the human. Apparatus  400  is one implementation of the command interface unit  102  and  FIG. 1  and  FIG. 2 . 
     The command interface unit  102  shown in  FIG. 4  includes an input device  402  that receives information in any one of a number of different communication methods. One implementation of a number of different input devices  402  is described in  FIG. 5 . The received information is processed in a two-pronged approach. In a first prong, the information is processed by an authority filter  316 . The authority  FIG. 316  analyzes the information and extracts from the information an indicator  318  of the authority of the operator. Thereafter, the information is processed by a command interpreter  402 . The command interpreter analyzes the information and extracts a command  310  from the information. Examples of commands  310  include “move up” “move down” “move forward” and “move backward.” In a second prong, the information is processed by a state-of-mind filter  312 . The state-of-mind filter  312  analyzes the information and extracts from the information indicators of the emotional state of the operator, indicators of the competency of the operator, and/or indicators of the state-of-mind of the operator  314 . 
     An authority engine  312  receives the command  310 , the state-of-mind  314  and the indicator of authority of the operator  318 . The authority engine  320  and analyzes the command  310 , the state-of-mind  314  and the indicator of authority of the operator  318  in reference to an authority database  322 . In one implementation the authority engine determines whether or not the command  310  is authorized by the authority of the operator  318 . If the command  310  is not authorized by the authority of the operator  318 , the command  310  is rejected. In another implementation the authority engine  320  determines whether or not the state-of-mind  314  of the operator is of a sufficient level for the command  310 . If the authority for the operator is not of a sufficient level for the command  310 , command  310  is rejected. If the authority for the operator is of a sufficient level for the command  310 , command  310  is accepted. 
     Command interface unit apparatus  400  provides command control of a patient-movement-actuator  114  of a patient-lifting-device through a variety of input mediums, such verbal audio input, hand-held keypad controllers synaptic activity sensor in reference or consideration to the authority and emotion, competency and state of mind of the operator from which the command is issued, with the added efficiency of not interpreting the command from the input information until after the authority and emotion, competency and state of mind of the operator, as represented in the input information, is evaluated. The multisensory command input of command interface unit apparatus  400  benefits people with physical difficulties by reducing if not completely eliminating the requirement to manually control the patient-movement-actuator  114 . 
       FIG. 5  is a block diagram of a plurality of input devices  500  that receive information in any one of a number of different communication methods, according to an implementation. Input devices  500  are implementations of the input devices  302  and  FIG. 3  and  FIG. 4 . 
     Input devices  302  include a conventional keyboard data receiver  502 , commonly known as a keyboard. Input devices  302  also include an audio data receiver  504 . Input devices also include a synaptic activity sensor  506 . The receivers  502  and  504  and the synaptic activity sensor  506  can be implemented either with a wireless connection to the command interface unit  102  and/or with a wired connection to the command interface unit  102 . Another input device that is not shown is a hand-held keypad controller that includes buttons for up, down, forward, backward and stop. The receivers  502  and  504 , the hand-held keypad controller, and the synaptic activity sensor  506  capture multisensory information  508  from an operator that is processed by the command interface unit  102  in  FIG. 1 ,  FIG. 2  and/or  FIG. 3 . The multiple input devices of in  FIG. 5  provide multisensory input to the command interface unit  102  in  FIG. 1 ,  FIG. 2  and/or  FIG. 3 . 
     A receiver that is not shown in  FIG. 5  is a pressure sensitive device (e.g. piezo electric device) mounted on and/or in the top of a tooth. The pressure sensitive device senses/reads/measures pressure, transmits an indication or representation of the pressure to a processor via a wireless connection. The pressure reading/measurement is interpreted as an indicator or command to an external device, such as a patient-lifting-device. An example of the command is a command to control horizontal speed of the patient-lifting-device. 
     Input device  302  in  FIG. 5  provides command control of a patient-movement-actuator  114  of a patient-lifting-device through a variety of input mediums, such verbal audio input, hand-held keypad controllers synaptic activity sensor in reference or consideration to the authority and emotion, competency and state of mind of the operator from which the command is issued.

The lift-device-controller  700  includes a user interface  702  for device configuration that is operable to display, receive and/or store device configuration information for a patient-movement-actuator, such as patient-movement-actuator  114  in  FIG. 1  and  FIG. 2 . The device configuration user interface  702  is operably coupled to a modifiable logic circuit  704  that is operable to control the patient-lifting-device. In one implementation, the modifiable logic circuit  704  is a field-programmable gate-array (FPGA) circuit in reference to the device configuration. 
     Apparatus components of  FIG. 1-7  can be embodied as computer hardware circuitry or as a computer-readable program, or a combination of both. 
     More specifically, in the computer-readable program implementation, the programs can be structured in an object-orientation using an object-oriented language such as Java, Smalltalk or C++, and the programs can be structured in a procedural-orientation using a procedural language such as COBOL or C. The software components communicate in any of a number of means that are well-known to those skilled in the art, such as application program interfaces (API) or interprocess communication techniques such as remote procedure call (RPC), common object request broker architecture (CORBA), Component Object Model (COM), Distributed Component Object Model (DCOM), Distributed System Object Model (DSOM) and Remote Method Invocation (RMI). In some implementations, the components execute on as few as one computer as in computer environment  1000  in  FIG. 10 , or on at least as many computers as there are components. In some implementations, the components execute on as few as one voice-recognition apparatus as in voice-recognition apparatus  1100  in  FIG. 11 , or on at least as many computers as there are components. 
     Method Implementations 
     In the previous section, apparatus of the operation of an implementation was described. In this section, the particular methods performed by a processor of such an implementation are described by reference to a series of flowcharts. 
       FIG. 8  is a flowchart of a method  800  to control a patient-lifting-device, according to an implementation. Method  800  receives information from a human and generates a command from the human information, in reference to authority of the human and the state of the mind of the human. Method  800  generates command(s) that are suitable to be processed by a processor in control of a patient-lifting-device. In some implementations, method  800  is performed by the command interface unit  102  and  FIG. 1  and  FIG. 2 . 
     Method  800  includes receiving  802  information from any one of a number of different communication devices.  FIG. 5  describes some implementations of communication devices. Method  800  includes processing the information by analyzing the information and extracting  804  a command from the information. Examples of the command include “move up” “move down” “move forward” and “move backward.” Method  800  includes processing the information by analyzing and extracting  806  from the information indicators of the emotional state of the operator, indicators of the competency of the operator, and/or indicators of the state-of-mind of the operator. 
     Method  800  includes processing the information by analyzing the information and extracting  808  from the information an indicator of the authority of the operator. In some implementations, extracting an indication of authority of the operator includes identifying the operator. For example, where the information  802  is audio information from a human speaker, the identity of the human speaker is determined and the authority of that speaker is then determined. In some implementations, the speech pattern of the human speaker is compared to a database of known humans. The database is created prior to the performance of method  800  from recorded speech sample recordings of humans who are authorized to enter the healthcare facility, such a healthcare providers, non-professional employees of the healthcare facility, patients, and friends, relatives and/or coworkers of the patient. Each human whose speech sample is recorded in the database is associated with a particular authority. An example of an authority is “full authority” in which the human is authorized to exercise or command all functions of the patient-lifting-device. Another example of an authority is “no authority in which the human is not authorized to exercise or command any function of the patient-lifting-device. In method  800 , the database is accessed and a comparison of the information  802  to the speech samples in the database is performed. When the comparing determines the identity of the human speaker, the authority of the identified human is accessed and used as the indicator of authority of the operator. 
     In method  800 , the command, the state-of-mind and the indicator of authority of the operator is analyzed  810  to an authority database to determine whether or not the command is authorized by the authority of the operator in consideration of the emotional state of the operator. If the command is not authorized by the authority and emotional state of the operator, the command is rejected  812 . In some implementations, rejecting  812  the command can include transmitting a notice of an attempted unauthorized command to supervisory personnel or law enforcement agency. If the command is determined to be authorized, the command is transmitted  814  to the processor (e.g.  106  in  FIG. 1 ) and the command  812  is performed by the patient-lifting-device. In some implementations, a log or journal of all extracted commands in action  804  and the determination  810  of the authority of the extracted commands is stored. 
     Method  800  provides command control of a patient-movement-actuator  114  through a variety of input mediums, such verbal audio input, hand-held keypad controllers synaptic activity sensor in reference or consideration to the authority and emotion, competency and state of mind of the operator from which the command is issued, with the added efficiency of not interpreting the command from the input information until after the authority and emotion, competency and state of mind of the operator, as represented in the input information, is evaluated. The multisensory command input of method  800  benefits people with physical difficulties by reducing if not completely eliminating the requirement to manually control the patient-movement-actuator  114 . 
       FIG. 9  is a flowchart of a method  900  to control a patient-lifting-device, according to an implementation. Method  900  receives information from a human and generates a command from the human information, in reference to authority of the human and the state of the mind of the human. Method  900  generates command(s) that are suitable to be processed by a processor in control of a patient-lifting-device. In some implementations, method  900  is performed by the command interface unit  102  and  FIG. 1  and  FIG. 2 . 
     Method  900  includes receiving  802  information from one of a number of different communication devices.  FIG. 5  describes some implementations of the different communication devices. 
     Method  900  includes processing the information by analyzing the information and extracting  808  from the information an indicator of the authority of the operator. In some embodiments, extracting an indication of authority of the operator includes identifying the operator. For example, where the information  802  is audio information from a human speaker, the identity of the human speaker is determined and the authority of that speaker is then determined. In some embodiments, the speech pattern of the human speaker is compared to a database of known humans. In method  900 , the database is accessed and a comparison of the information  802  to the speech samples in the database is performed. When the comparing determines the identity of the human speaker, the authority of the identified human is accessed and used as the indicator of authority of the operator. 
     Method  900  includes processing the information by analyzing the information and extracting  902  a command from the information. Examples of the command include “move up” “move down” “move forward” and “move backward.” Method  900  includes processing the information by analyzing and extracting  806  from the information indicators of the emotional state of the operator, indicators of the competency of the operator, and/or indicators of the state-of-mind of the operator. 
     In method  900 , the command, the state-of-mind and the indicator of authority of the operator is analyzed  810  to an authority database to determine whether or not the command is authorized by the authority of the operator in consideration of the emotional state of the operator. If the command is not authorized by the authority and emotional state of the operator, the command is rejected  812 . In some implementations, rejecting  812  the command can include transmitting a notice of an attempted unauthorized command to supervisory personnel or law enforcement agency. If the command is determined to be authorized, the command is transmitted  814  to the processor (e.g.  106  in  FIG. 1 ) and the command  812  is performed by the patient-lifting-device. In some implementations, a log or journal of all extracted commands in action  902  and the determination  810  of the authority of the extracted commands is stored. 
     Method  900  provides command control of a patient-movement-actuator  114  through a variety of input mediums, such verbal audio input, hand-held keypad controllers synaptic activity sensor in reference or consideration to the authority and emotion, competency and state of mind of the operator from which the command is issued, with the added efficiency of not interpreting the command from the input information until after the authority and emotion, competency and state of mind of the operator, as represented in the input information, is evaluated. The multisensory command input of method  900  benefits people with physical difficulties by reducing if not completely eliminating the requirement to manually control the patient-movement-actuator  114 . 
     In some implementations, methods  800 - 900  are implemented as a sequence of instruction which, when executed by a processor, such as processor unit  1004  in  FIG. 10 , processor  106  in  FIG. 1  and  FIG. 2 , or cause the processor to perform the respective method. In other implementations, methods  800 - 900  are implemented as a computer-accessible medium having executable instructions capable of directing a processor, such as processor unit  1004  in  FIG. 10 , to perform the respective method. In some implementations, methods  800 - 900  are implemented as a sequence of instructions which, when executed by a processor, such as microcontroller, processor or microprocessor  1102  in  FIG. 11 , cause the microcontroller, processor or microprocessor  1102  to perform the respective method. In other implementations, methods  800 - 900  are implemented as a computer-accessible medium having executable instructions capable of directing a processor, such as microcontroller, processor or microprocessor  1102  in  FIG. 11 , to perform the respective method. In varying implementations, the medium is a magnetic medium, an electronic medium, or an optical medium. 
     Hardware and Operating Environment 
       FIG. 10  is a block diagram of a hardware and operating environment  1000  in which different implementations can be practiced. The description of  FIG. 10  provides an overview of computer hardware and a suitable computing environment in conjunction with which some implementations can be implemented Implementations are described in terms of a computer executing computer-executable instructions. However, some implementations can be implemented entirely in computer hardware in which the computer-executable instructions are implemented in read-only memory. Some implementations can also be implemented in client/server computing environments where remote devices that perform tasks are linked through a communications network. Program modules can be located in both local and remote memory storage devices in a distributed computing environment. 
       FIG. 10  illustrates an example of a computer environment  1000  useful in the context of the environment of  FIG. 1-9 , in accordance with an implementation. The computer environment  1000  includes a computation resource  1002  capable of implementing the processes described herein. It will be appreciated that other devices can alternatively used that include more components, or fewer components, than those illustrated in  FIG. 10 . 
     The illustrated operating environment  1000  is only one example of a suitable operating environment, and the example described with reference to  FIG. 10  is not intended to suggest any limitation as to the scope of use or functionality of the implementations of this disclosure. Other well-known computing systems, environments, and/or configurations can be suitable for implementation and/or application of the subject matter disclosed herein. 
     The computation resource  1002  includes one or more processors or processing units  1004 , a system memory  1006 , and a bus  1008  that couples various system components including the system memory  1006  to processor(s)  1004  and other elements in the environment  1000 . The bus  1008  represents one or more of any of several types of bus structures, including a memory bus or memory controller, a peripheral bus, an accelerated graphics port and a processor or local bus using any of a variety of bus architectures, and can be compatible with SCSI (small computer system interconnect), or other conventional bus architectures and protocols. 
     The system memory  1006  includes nonvolatile read-only memory (ROM)  1010  and random access memory (RAM)  1012 , which can or can not include volatile memory elements. A basic input/output system (BIOS)  1014 , containing the elementary routines that help to transfer information between elements within computation resource  1002  and with external items, typically invoked into operating memory during start-up, is stored in ROM  1010 . 
     The computation resource  1002  further can include a non-volatile read/write memory  1016 , represented in  FIG. 10  as a hard disk drive, coupled to bus  1008  via a data media interface  1017  (e.g., a SCSI, ATA, or other type of interface); a magnetic disk drive (not shown) for reading from, and/or writing to, a removable magnetic disk  1020  and an optical disk drive (not shown) for reading from, and/or writing to, a removable optical disk  1026  such as a CD, DVD, or other optical media. 
     The non-volatile read/write memory  1016  and associated computer-readable media provide nonvolatile storage of computer-readable instructions, data structures, program modules and other data for the computation resource  1002 . Although the exemplary environment  1000  is described herein as employing a non-volatile read/write memory  1016 , a removable magnetic disk  1020  and a removable optical disk  1026 , it will be appreciated by those skilled in the art that other types of computer-readable media which can store data that is accessible by a computer, such as magnetic cassettes, FLASH memory cards, random access memories (RAMs), read only memories (ROM), and the like, can also be used in the exemplary operating environment. 
     A number of program modules can be stored via the non-volatile read/write memory  1016 , magnetic disk  1020 , optical disk  1026 , ROM  1010 , or RAM  1012 , including an operating system  1030 , one or more application programs  1032 , other program modules  1034  and program data  1036 . Examples of computer operating systems conventionally employed include the NUCLEUS® operating system, the LINUX® operating system, and others, for example, providing capability for supporting application programs  1032  using, for example, code modules written in the C++® computer programming language. 
     A user can enter commands and information into computation resource  1002  through input devices such as input media  1038  (e.g., keyboard/keypad, tactile input or pointing device, mouse, foot-operated switching apparatus, joystick, touchscreen or touchpad, microphone, antenna etc.). Such input devices  1038  are coupled to the processing unit  1004  through a conventional input/output interface  1042  that is, in turn, coupled to the system bus. A monitor  1050  or other type of display device is also coupled to the system bus  1008  via an interface, such as a video adapter  1052 . 
     The computation resource  1002  can include capability for operating in a networked environment using logical connections to one or more remote computers, such as a remote computer  1060 . The remote computer  1060  can be a personal computer, a server, a router, a network PC, a peer device or other common network node, and typically includes many or all of the elements described above relative to the computation resource  1002 . In a networked environment, program modules depicted relative to the computation resource  1002 , or portions thereof, can be stored in a remote memory storage device such as can be associated with the remote computer  1060 . By way of example, remote application programs  1062  reside on a memory device of the remote computer  1060 . The logical connections represented in  FIG. 10  can include interface capabilities, e.g., such as interface capabilities in  FIG. 5 , a storage area network (SAN, not illustrated in  FIG. 10 ), local area network (LAN)  1072  and/or a wide area network (WAN)  1074 , but can also include other networks. 
     Such networking environments are commonplace in modern computer systems, and in association with intranets and the Internet. In certain implementations, the computation resource  1002  executes an Internet Web browser program (which can optionally be integrated into the operating system  1030 ), such as the “Internet Explorer®” Web browser manufactured and distributed by the Microsoft Corporation of Redmond, Wash. 
     When used in a LAN-coupled environment, the computation resource  1002  communicates with or through the local area network  1072  via a network interface or adapter  1076 . When used in a WAN-coupled environment, the computation resource  1002  typically includes interfaces, such as a modem  1078 , or other apparatus, for establishing communications with or through the WAN  1074 , such as the Internet. The modem  1078 , which can be internal or external, is coupled to the system bus  1008  via a serial port interface. 
     In a networked environment, program modules depicted relative to the computation resource  1002 , or portions thereof, can be stored in remote memory apparatus. It will be appreciated that the network connections shown are exemplary, and other means of establishing a communications link between various computer systems and elements can be used. 
     A user of a computer can operate in a networked environment using logical connections to one or more remote computers, such as a remote computer  1060 , which can be a personal computer, a server, a router, a network PC, a peer device or other common network node. Typically, a remote computer  1060  includes many or all of the elements described above relative to the computer  1000  of  FIG. 10 . 
     The computation resource  1002  typically includes at least some form of computer-readable media. Computer-readable media can be any available media that can be accessed by the computation resource  1002 . By way of example, and not limitation, computer-readable media can comprise computer storage media and communication media. 
     Computer storage media include volatile and nonvolatile, removable and non-removable media, implemented in any method or technology for storage of information, such as computer-readable instructions, data structures, program modules or other data. The term “computer storage media” includes, but is not limited to, RAM, ROM, EEPROM, FLASH memory or other memory technology, CD, DVD, or other optical storage, magnetic cassettes, magnetic tape, magnetic disk storage or other magnetic storage devices, or any other media which can be used to store computer-intelligible information and which can be accessed by the computation resource  1002 . 
     Communication media typically embodies computer-readable instructions, data structures, program modules or other data, represented via, and determinable from, a modulated data signal, such as a carrier wave or other transport mechanism, and includes any information delivery media. The term “modulated data signal” means a signal that has one or more of its characteristics set or changed in such a manner as to encode information in the signal in a fashion amenable to computer interpretation. 
     By way of example, and not limitation, communication media include wired media, such as wired network or direct-wired connections, and wireless media, such as acoustic, RF, infrared and other wireless media. The scope of the term computer-readable media includes combinations of any of the above. 
     The computer  1002  can function as one or more of the control segments, via implementation of the processes in  FIGS. 8-9 , respectively, as one or more computer program modules. 
       FIG. 11  is a block diagram of a voice-recognition apparatus  1100  to control a patient-lifting-device, according to an implementation. The voice-recognition apparatus  1100  is one implementation of voice-recognition unit  604  in  FIG. 6 . The voice-recognition apparatus  1100  receives input from any one of a number of input mediums, such as audio, and therefrom controls a patient-lifting-device. The voice-recognition apparatus  1100  can fit inside the housing of conventional patient-lifting-device and can communicate with and control conventional patient-lifting-device using the conventional existing electrical circuitry of patient-lifting-device. The voice-recognition apparatus  1100  helps improve control of the patient-lifting-device by receiving input from any one of a number of input mediums, such as audio. In the example of audio, the voice-recognition apparatus  1100  improves the ease and convenience with which an operator can control the patient-lifting-device by providing a voice interface to the patient-lifting-device. In general, the voice-recognition apparatus  1100  improves the ease and convenience with which an operator can control the patient-lifting-device by providing a command interface to the patient-lifting-device other than a handheld control device. 
     Voice-recognition apparatus  1100  includes a microcontroller, processor or microprocessor  1102 . The microcontroller, processor or microprocessor  1102  is one example of the processor  106  in  FIG. 1  and  FIG. 2 . 
     One example of the microcontroller, processor or microprocessor  1102  is RSC 6502 microcontroller. The 6502 is an 8-bit processor with a 16-bit address bus. The internal logic runs at the same speed as the external clock rate, and having clock speeds typically in the neighborhood of 1 or 2 MHz. The 6502 has a relatively simplistic state machine implemented by combinatorial (clockless) logic. A two phase clock (supplying two synchronizations per cycle) can thereby control the whole machine-cycle directly. The 6502 microcontroller is not sequenced by a microcode read-only-memory but uses a programmable logic array for instruction decoding and sequencing. Like most typical eight-bit microprocessors, the 6502 microcontroller does some limited overlapping of fetching and execution. The low clock frequency moderates the speed requirement of memory and peripherals attached to the 6502 microcontroller, as only about 50% of the clock cycle is available for memory access (due to the asynchronous design, this percentage varies strongly among chip versions). The 6502 microcontroller is minimalistically engineered and efficiently manufactured and therefore inexpensive. Like its precursor, the Motorola 6800 (but unlike Intel 8080 and similar microprocessors) the 6502 microcontroller has very few registers. The registers of the 6502 microcontroller include one 8-bit accumulator register (A), two 8-bit index registers (X and Y), an 8-bit processor status register (P), an 8-bit stack pointer (S), and a 16-bit program counter (PC). The subroutine call/scratchpad stacks address space is hardwired to memory page $01, i.e. the address range $0100-$01 FF (256-511). Software access to the stack is performed via four implied addressing mode instructions whose functions are to push or pop (pull) the accumulator or the processor status register. The same stack is also used for subroutine calls via the JSR (Jump to Subroutine) and RTS (Return from Subroutine) instructions, and for interrupt handling. The 6502 microcontroller uses the index and stack registers effectively with several addressing modes, including a fast “direct page” or “zero page” mode, similar to that found on the PDP-8, that accessed memory locations from address 0 to 255 with a single 8-bit address (saving the cycle normally required to fetch the high-order byte of the address)—code for the 6502 use the zero page much as code for other processors would have used registers. Addressing modes also include implied (1 byte instructions); absolute (3 bytes); indexed absolute (3 bytes); indexed zero-page (2 bytes); relative (2 bytes); accumulator (1); indirect,x and indirect,y (2); and immediate (2). Absolute mode is a general-purpose mode. Branch instructions use a signed 8-bit offset relative to the instruction after the branch; the numerical range −128 . . . 127 therefore translates to 128 bytes backward and 127 bytes forward from the instruction following the branch (which is 126 bytes backward and 129 bytes forward from the start of the branch instruction). Accumulator mode uses the accumulator as an effective address, and did not need any operand data. Immediate mode uses an 8-bit literal operand. The indirect modes are useful for array processing and other looping. With the 5/6 cycle “(indirect),y” mode, the 8-bit Y register is added to a 16-bit base address in zero page, located by a single byte following the opcode. As the resulting address could be anywhere in the 16-bit memory range, the Y register is a true index register, as opposed to the 6800, which had one 16-bit address register. Incrementing the index register to walk the array byte-wise took only two additional cycles. With the less frequently used “(indirect,x)” mode the effective address for the operation is found at the zero page address formed by adding the second byte of the instruction to the contents of the X register. Using the indexed modes, the zero page effectively acted as a set of 128 additional (though very slow) address registers. The 6502 also includes a set of binary coded decimal (BCD) instructions, a feature normally implemented in software. Placing the CPU into BCD allowed numbers to be manipulated in base-10, with a set of conversion instructions to convert between base-10 and binary (base-2). For instance, with the “D” flag set, 99+1 would result in 00 and the carry flag being set. These instructions remove the need to convert numbers for display in the BASIC interpreter itself. However, this feature means other useful instructions can not be implemented easily, and is sometimes removed to make room for custom instructions. The RSC 6502 microcontroller is merely one example of microcontroller, processor or microprocessor that can be used in the voice-recognition apparatus  1100 . The RSC 6502 microcontroller has been manufactured by Conexant Systems at 4000 MacArthur Boulevard, Newport Beach, Calif.

     And some implementations, the microcontroller, processor or microprocessor  1102  is operably coupled to a program/run switch  1106  that is set to indicate the mode that the microcontroller, processor or microprocessor  1102  is operating. When the microcontroller, processor or microprocessor  1102  is being programmed, the program/run switch  1106  is set to program.

     In other implementations, the microcontroller, processor or microprocessor  1102  (microprocessor/microcontroller/processor) includes memory. In some implementations in which the microprocessor/microcontroller/processor  1102  includes memory, the microprocessor/microcontroller/processor  1102  provides an economical wireless voice control and communications system. The microprocessor/microcontroller/processor  1102  incorporates voice recognition, infrared (IR) and radio frequency (RF) wireless protocols including Zigbee and Bluetooth wireless protocols with positional awareness and a complex programmable logic device (CPLD) interface. The microprocessor/microcontroller/processor  1102  communicates with and controls multi-sensory controls for products from microwaves and washing machines to spacecraft. The microprocessor/microcontroller/processors  1102  are selected from both 16-bit and 32-bit devices. The microprocessor/microcontroller/processor  1102  having 16-bit radio-frequency (RF) interfaces are well-suited for applications such as wireless keyboard/mouse, wireless voice-over-IP (VoIP), remote controls, wireless gaming accessories, home and building automation applications such as alarm and security systems, automatic meter reading systems, active radio-frequency identification (RFID) systems and other monitoring and control systems. 
     Microprocessor/microcontroller/processors  1102  having 32-bit word-length include high performance integrated peripherals designed for real-time control applications. An optimized core of the microprocessor/microcontroller/processor  1102  performs multiple complex control algorithms at speeds necessary for demanding control applications. Integrated peripherals such as a 16-channel, 12-bit analog-to-digital conversion (ADC) running at up to 12.5 megasamples per second and high resolution pulse-width modulation (PWM) modules with 150 picosecond resolution provide sufficient bandwidth for communication with analog devices. Further including the serial peripheral interface (SPI), universal asynchronous receiver/transmitter (UART), inter-IC (I2C), campus area network (CAN), and multi-channel buffered serial port (McBSP) communication peripherals provides device control on a single microprocessor/microcontroller/processor  1102 . Applications include appliances, alternating current/direct current (AC/DC), direct current/alternating (DC/AC) and direct current/direct current (DC/DC) digital power supplies, solar inverters, digital motor control, and power line communication.

Examples of the patient-lifting-device include the two dimensional patient-lifting-device  1300  in  FIG. 13  and a one dimensional patient-lifting-device (not shown). One implementation of the patient-movement-actuator  114  for a two dimensional patient-lifting-device (e.g. the two dimensional patient-lifting-device  1300  in  FIG. 13 ) implements a double-pole (DP) double-throw (DT) relay for each direction of movement of the two dimensional patient-lifting-device. The lift-device-controller  110  in  FIG. 11  is one example of lift-device-controller  110  in  FIG. 1  and  FIG. 2 . The lift-device-controller  110  and the patient-movement-actuator  114  are not a part of the voice-recognition apparatus  1100  as indicated by the dashed border lines of the lift-device-controller  110  and the patient-movement-actuator  114 , but the lift-device-controller  110  and the patient-movement-actuator  114  is shown in the  FIG. 11  to provide a more comprehensive view of the configuration and interoperability of the voice-recognition apparatus  1100 , the lift-device-controller  110  and the patient-movement-actuator  114 .

Voice-recognition apparatus  1200  provides verbal command control of the patient-movement-actuator  114 . The verbal command input benefits people with physical difficulties by reducing if not completely eliminating the requirement to manually control the patient-movement-actuator  114 . 
       FIG. 13  is a block diagram of a two dimensional patient-lifting-device  1300 , according to an implementation that is specifically adapted for lifting a patient out of a bed. The two dimensional patient-lifting-device  1300  in  FIG. 13  is one example of patient-lifting devices. 
     Patient-lifting-device  1300  includes vertical main supports  1302  and  1304  that are optionally supported by wheels  1306  and  1308  for movement on the ground. Patient-lifting-device  1300  also includes a horizontal support  1310  that is fixedly attached to the vertical main supports  1302  and  1304 . In the implementation shown in  FIG. 13 , a seat or hammock  1312  is attached to the horizontal support  1310  via lines  1314 ,  1316 ,  1318  and  1320 , although other implementations of the seat or hammock  1312  are well-known. An electric or hydraulic control box  1322  is slidably attached to the horizontal support  1310  through a rail (not shown) and the lines  1314 ,  1316 ,  1318  and  1320  are attached to the control box  1322  through a line  1324 . The control box  1322  causes the line  1324  to be extended or retracted. A patient is placed in the seat or hammock  1312  for movement. As the line  1324  is extended, the hammock or seat  1312  is lowered downward, thus causing the patient in the hammock or seat  1312  to move downward. As the line  1324  is retracted, the seat or hammock  1312  is moved upward, thus causing the patient in the hammock or seat  1312  to move upwards. In addition the control box  1322  is operable to move horizontally along the horizontal support  1310  on the rail. 
     In some implementations, the control box  1322  includes various apparatus and systems described in this disclosure that provide control of the patient-lifting-device  1300  from various stimulus such as audio voice input. Examples of the various apparatus and systems that are included in the control box  1322  include the command interface unit  102 , processor  106 , lift-device-controller  110  and/or patient-movement-actuator  114  in  FIG. 1  and  FIG. 2 ; and control box  1322  can be operably coupled to the keyboard data receiver  502 , voice data receiver  504 , a synaptic activity sensor  506  in  FIG. 5 , the microphone  602  and or voice-recognition unit  604  in  FIG. 6 , the device configuration user interface  702  and/or the modifiable logic circuit  704  in  FIG. 7 , the electrical devices in  FIGS. 10-11  and  14 , and other tangible systems that perform methods  300 ,  400 ,  800  and/or  900 . 
     In some implementations, the two dimensional patient-lifting-device  1300  includes a hand-held keypad controller  1326  that includes buttons for up, down, forward, backward and stop  1326  that is electrically coupled to the patient-movement-actuator  114  in the control box  1322  via a line  1328 , the hand-held keypad controller  1326  providing signals that direct movement of the line  1324  and movement of the control box  1322  along the horizontal support  1310 . In some implementations, control initiated from the hand-held keypad controller  1326  overrides control initiated from other input means. 
     In some implementations, the only input devices for commands in the patient-lifting-device  1300  are a microphone  602  operably coupled to a voice data receiver  504 ; and hand-held keypad controller  1326 . In such implementations, a keyboard data receiver and a synaptic activity sensor  506  are not included in the patient-lifting-device  1300 . 
     Some implementations of the two dimensional patient-lifting-device  1300  include a charging unit (not shown) in the horizontal support  1310  and/or the control box  1322  to provide power for recharging a battery. The battery can be mounted either in the control box  1322  or the horizontal support  1310 . The charging unit is electrically coupled to a power cord having male prongs on the other end from the charging unit that are suitable to plug into a standard residential electrical wall outlet female receptacle. 
     Some implementations of the two dimensional patient-lifting-device  1300  are a portable patient-lifting-device that fits in doorways. 
       FIG. 14  is a block diagram of a patient-movement-actuator  1400  of a patient-lifting-device, according to an implementation using DPDT relays. Patient-movement-actuator  1400  is one implementation of the patient-movement-actuator  114  in  FIGS. 1 ,  2 ,  11  and  12  for a two dimensional patient-lifting-device, such as two dimensional patient-lifting-device  1300  in  FIG. 13 , that implements a normally-open double-pole-double-throw (DPDT) relay for each direction of movement of the two dimensional patient-lifting-device. Two-dimensional motion consists of movement in four directions, hence patient-movement-actuator  1400  consists of four normally-open DPDT relays. Other implementations of patient-movement-actuator  1400  that do not have the safety features of patient-movement-actuator  1400  implement single-pole-single-throw (SPST) relays. 
     To command movement in a particular direction, the corresponding relay is actuated. To actuate the patient-lifting-device in an upward direction, DPDT relay  1402  is actuated by setting voltage “high” (e.g. 3 volts) on pin “P2.0”  1403 . When DPDT relay  1402  is actuated, the normally-open DPDT relay  1402  is closed, thereupon a positive electric current will flow from the positive terminal  1404  of the 24 volt DC battery  1406 , through DPDT relay  1408 , and through DPDT relay  1402  to Terminal A  1410  of lifting motor  1412  and also when DTDT relay  1402  is actuated, a negative electric current will flow from the negative terminal  1414  of the 24 volt DC battery  1406 , through DPDT relay  1402  to Terminal B  1416  of lifting motor  1412 , thus providing electric current to lifting motor  1412  in a polarity that will retract a line coupled to the lifting motor  1412 , thereupon lifting the seat or hammock  1312 . 
     To actuate the patient-lifting-device in a downward direction, DPDT relay  1408  is actuated by setting voltage “high” (e.g. 3 volts) on pin “P2.1”  1418 . When DPDT relay  1408  is actuated, the normally-open DPDT relay  1408  becomes closed, thereupon a negative electric current will flow from the negative terminal  1414  of the 24 volt DC battery  1406 , through DPDT relay  1402 , and through DPDT relay  1408  to Terminal A  1410  of lifting motor  1412  and also when DTDT relay  1408  is actuated, a positive electric current will flow from the positive terminal  1404  of the 24 volt DC battery  1406 , through DPDT relay  1408  to Terminal B  1416  of lifting motor  1412 , thus providing electric current to lifting motor  1412  in a polarity that will extend a line coupled to the lifting motor  1412 , thereupon lowering the seat or hammock  1312 . 
     Please note the safety feature in the serial wiring of DTDT relay  1402  and DPDT relay  1408 . The safety feature lies in that positive electric current will flow from the positive terminal  1404  of the 24 volt DC battery  1406 , through DPDT relay  1408 , and through DPDT relay  1402  to Terminal A  1410  of lifting motor  1412  when DPDT relay  1408  is not actuated. Positive electric current will not flow from the positive terminal  1404  of the 24 volt DC battery  1406 , through DPDT relay  1408 , and through DPDT relay  1402  to Terminal A  1410  of lifting motor  1412  when DPDT relay  1408  is actuated. Therefore, if somehow both DPDT relay  1402  and DPDT relay  1408  are simultaneously actuated, no current will flow to the lifting motor  1412 , thus preventing both positive electric current and negative electric from simultaneously flowing to Terminal A  1410  of lifting motor  1412  and preventing both positive electric current and negative electric from simultaneously flowing to Terminal B  1416  of lifting motor  1412 . 
     Other implementations use other power sources in place of the 24 volt DC battery  1406 . 
     To actuate the patient-lifting-device in a forward traversal direction, DPDT relay  1422  is actuated by setting voltage “high” (e.g. 3 volts) on pin “P2.2”  1423 . When DPDT relay  1422  is actuated, the normally-open DPDT relay  1422  is closed, thereupon a positive electric current will flow from the positive terminal  1404  of the 24 volt DC battery  1406 , through DPDT relay  1428 , and through DPDT relay  1422  to Terminal A  1430  of traversing motor  1432  and also when DTDT relay  1422  is actuated, a negative electric current will flow from the negative terminal  1434  of the 24 volt DC battery  1406 , through DPDT relay  1422  to Terminal B  1436  of traversing motor  1432 , thus providing electric current to traversing motor  1432  in a polarity that will traverse in a forward direction the line coupled to the traversing motor  1432 , thereupon moving the seat or hammock  1312  forward. 
     To actuate the patient-lifting-device in a backward direction, DPDT relay  1428  is actuated by setting voltage “high” (e.g. 3 volts) on pin “P2.3”  1438 . When DPDT relay  1428  is actuated, the normally-open DPDT relay  1428  becomes closed, thereupon a negative electric current will flow from the negative terminal  1434  of the 24 volt DC battery  1406 , through DPDT relay  1422 , and through DPDT relay  1428  to Terminal A  1430  of traversing motor  1432  and also when DTDT relay  1428  is actuated, a positive electric current will flow from the positive terminal  1404  of the 24 volt DC battery  1406 , through DPDT relay  1428  to Terminal B  1436  of traversing motor  1432 , thus providing electric current to traversing motor  1432  in a polarity that will traverse in a backward direction the line coupled to the traversing motor  1432 , thereupon lowering the seat or hammock  1312 . 
     Please note the safety feature in the serial wiring of DTDT relay  1422  and DPDT relay  1428 . The safety feature lies in that positive electric current will flow from the positive terminal  1404  of the 24 volt DC battery  1406 , through DPDT relay  1428 , and through DPDT relay  1422  to Terminal A  1430  of traversing motor  1432  when DPDT relay  1428  is not actuated. Positive electric current will not flow from the positive terminal  1404  of the 24 volt DC battery  1406 , through DPDT relay  1428 , and through DPDT relay  1422  to Terminal A  1430  of traversing motor  1432  when DPDT relay  1428  is actuated. Therefore, if somehow both DPDT relay  1422  and DPDT relay  1428  are simultaneously actuated, no current will flow to the traversing motor  1432 , thus preventing both positive electric current and negative electric from simultaneously flowing to Terminal A  1430  of traversing motor  1432  and preventing both positive electric current and negative electric from simultaneously flowing to Terminal B  1436  of traversing motor  1432 . 
     A DPDT relay consists of two separate switches that operate at the same time, each one with normally open and normally closed contact through a common connector. Each of the two contacts on the switch can be routed in different ways, depending on the position of the switch. An example of a switch is a mini-toggle switch or a switch using a push or pull control. 
     DPDT relay switches commonly use polarity reversal. That is why some variations of the DPDT relay, such as the cross-over switches, are internally wired for that purpose. The cross-over switches have only four terminals or connections, as opposed to six on a DPDT relay. Two connections are used for the outputs and the other two for the inputs. The switch then selects either normal or reversed polarity when connected to any direct current source such as a battery. 
     A DPDT relay has a single coil with two arms that move simultaneously. Inside of the DPDT relay, there are two separate single-pole-double-throw (SPDT) switch mechanisms. 
     In some implementations of a two-dimensional patient-lifting-device, a control line that is associated with upward movement from a voice-recognition apparatus and a control line that is associated with upward movement from a hand-held keypad controller are both electrically coupled to pin “P2.0”  1403 , a control line that is associated with downward movement from a voice-recognition apparatus and a control line that is associated with downward movement from a hand-held keypad controller are both electrically coupled to pin “P2.1”  1418 , a control line that is associated with forward movement from a voice-recognition apparatus and a control line that is associated with forward movement from a hand-held keypad controller are both electrically coupled to pin “P2.1”  1423 , and a control line that is associated with backward movement from a voice-recognition apparatus and a control line that is associated with backward movement from a hand-held keypad controller are both electrically coupled to pin “P2.2”  1428 .
