The temperature control subsystem may comprise one or more heating elements and one or more air moving devices that may vary the temperature of a musical instrument that is stored within the instrument case. As a non-limiting example, the musical instrument may be a flute. Storing the musical instrument within the instrument case may eliminate the need for the musical instrument to acclimate to room temperature or be warmed after being in a cold environment and may prevent thermal contraction and expansion which may alter the tonal qualities of the musical instrument. The operator interface may be adapted for a user to monitor and control the operation of the temperature control subsystem. ## Claims ### Claim 1 A wind instrument electronic warming case comprising: an instrument case, a temperature control subsystem, and an operator interface;

wherein a bottom shaped insert is coupled to the interior of the bottom section; wherein the bottom shaped insert comprises a plurality of cavities; wherein the plurality of cavities provide contours that are adapted to accept the musical instrument once the musical instrument has been disassembled; wherein a top shaped insert is coupled to the interior of the top section; wherein the top shaped insert is shaped to fit around the temperature control subsystem. ### Claim 2 (depends on 1) The wind instrument electronic warming case according to claim 1 wherein the instrument case is a container for storing the musical instrument; wherein the bottom section and the top section form a rigid hollow shell; wherein shaped inserts within the instrument case adapt the instrument case to hold the musical instrument and the temperature control subsystem. ### Claim 3 (depends on 2) The wind instrument electronic warming case according to claim 2 wherein the bottom shaped insert and the top shaped insert are made from a non-scratch material such that the finish of the musical instrument is not damaged when the musical instrument is stored within the instrument case. ### Claim 4 (depends on 3) The wind instrument electronic warming case according to claim 3 wherein the bottom shaped insert and the top shaped insert are made from foam; wherein the bottom shaped insert and the top shaped insert are lined with velvet. ### Claim 5 (depends on 3) The wind instrument electronic warming case according to claim 3 wherein the instrument case comprises one or more latches located on the side of the instrument case that is opposite the one or more hinges; wherein the one or more latches hold the instrument case closed until the one or more latches are released. ### Claim 6 (depends on 5) The wind instrument electronic warming case according to claim 5 wherein the temperature control subsystem comprises the one or more heating elements, the one or more air moving devices, and control electronics; wherein the one or more heating elements heat air within the instrument case when energized; wherein the one or more air moving devices move the air within the instrument case when energized; wherein the control electronics controls the energization of the one or more heating elements and the one or more air moving devices to achieve a warming or cooling of the musical instrument stored within the instrument case. ### Claim 7 (depends on 6) The wind instrument electronic warming case according to claim 6 wherein the one or more heating elements convert electrical energy into heat; wherein the amount of heating produced by the one or more heating elements varies based upon one or more characteristics of the electrical energy applied to the one or more heating elements. ### Claim 8 (depends on 7) The wind instrument electronic warming case according to claim 7 wherein the one or more air moving devices force the movement of the air; wherein the one or more air moving devices are electromechanical in nature. ### Claim 9 (depends on 8) The wind instrument electronic warming case according to claim 8 wherein the one or more air moving devices move the air within the instrument case such that the air passes over the one or more heating elements; wherein the one or more air moving devices transfer heat from the one or more heating elements to the musical instrument via the flow of the air. ### Claim 10 (depends on 9) The wind instrument electronic warming case according to claim 9 wherein energization of the one or more air moving devices while the one or more heating elements are not energized results in a non-heated flow of the air over the musical instrument and has a cooling effect upon the musical instrument. ### Claim 11 (depends on 10) The wind instrument electronic warming case according to claim 10 wherein the one or more air moving devices are vented to the outside such that the one or more air moving devices draw the air in from outside of the instrument case, expel the air out of the instrument case, or both. ### Claim 12 (depends on 11) The wind instrument electronic warming case according to claim 11 wherein the control electronics comprises a microcontroller and one or more temperature sensors; wherein the microcontroller is a microprocessor comprising non-volatile memory for storing a control program, read/write memory for storing data and intermediate computations, one or more input/output ports for interfacing with circuitry located outside of the microcontroller, and a timer circuit for timing intervals. ### Claim 13 (depends on 12) The wind instrument electronic warming case according to claim 12 wherein the one or more temperature sensors measure the temperature of the air and report the temperature to the microcontroller as one or more electrical signals; wherein the one or more temperature sensors are positioned in the flow of the air. ### Claim 14 (depends on 13) The wind instrument electronic warming case according to claim 13 wherein in at least one mode of operation, the control electronics maintains the temperature of the air at a setpoint temperature by energizing and de-energizing the one or more heating elements and/or the one or more air moving devices. ### Claim 15 (depends on 14) The wind instrument electronic warming case according to claim 14 wherein the operator interface comprises operator controls and an operator display; wherein the operator interface is adapted for the user to interact with the wind instrument electronic warming case for purposes of monitoring and controlling operation of the wind instrument electronic warming case. ### Claim 16 (depends on 15) The wind instrument electronic warming case according to claim 15 wherein the operator controls comprises a power control, a warm control, a cool control, an up control, and a down control; wherein the operator controls are electrically coupled to the microcontroller such that the microcontroller detects activations of the operator controls; wherein the power control energizes and de-energizes the wind instrument electronic warming case; wherein the warm control selects a heating mode of operation which results in energization of the one or more heating elements with or without the one or more air moving devices; wherein the cool control selects a cooling mode of operation which results in energization of the one or more air moving devices without the one or more heating elements; wherein the up control increases the setpoint temperature; wherein the down control decreases the setpoint temperature. ### Claim 17 (depends on 16) The wind instrument electronic warming case according to claim 16 wherein the operator display is adapted to display a numeric value to the user. ### Claim 18 (depends on 17) The wind instrument electronic warming case according to claim 17 wherein the operator display comprises a four digit numeric display and an AM/PM indicator. ### Claim 19 (depends on 18) The wind instrument electronic warming case according to claim 18 wherein one or more batteries comprise one or more energy-storage devices;
