## Abstract

Systems and methods for controlling measurement units for a medical scale. One system includes a removable head unit configured to couple to a medical scale platform. The removable head unit includes a human machine interface (HMI) and an electronic processor coupled to the human machine interface. The electronic processor is configured to receive, via the HMI, a first user input selecting a permanent lock mode. The electronic processor is configured to, in response to receiving the user input, present a first authentication request and receive a second user input including a first authentication token. The electronic processor is configured to, when the first authentication token is valid, present a measurement unit selection prompt. The electronic processor is configured to receive a second user input selecting a measurement unit and, in response to receiving the second user input, activate the permanent lock mode based on the selected measurement unit.

## Claims

### Claim 1

A system for controlling measurement units for a medical scale, the system comprising:
a head unit configured to couple to a medical scale platform, the head unit including a memory, an input/output interface, and an electronic processor coupled to the memory and the input/output interface, and configured to:
receive, from a remote computing device communicatively coupled to the head unit, a first user input selecting a permanent lock mode;
in response to receiving the first user input selecting the permanent lock mode, present, on the remote computing device, a measurement unit selection prompt;
in response to presenting the measurement unit selection prompt, receive, from the remote computing device, a second user input selecting a measurement unit;
in response to receiving the second user input selecting the measurement unit, activate the permanent lock mode based on the selected measurement unit by setting a value in the memory;
detect a reset dongle attached to the input/output interface; and
in response to detecting the reset dongle, deactivate the permanent lock mode by erasing the value without altering scale calibration data stored in the memory.

### Claim 2 (depends on 1)

The system of claim 1, wherein the electronic processor is further configured to:
in response to receiving the second user input, present, on the remote computing device, a confirmation prompt;
receive, from the remote computing device, a third user input; and
when the third user input confirms the selection of the permanent lock mode, activate the permanent lock mode based on the selected measurement unit.

### Claim 3 (depends on 1)

The system of claim 1, wherein the electronic processor is further configured to:
in response to receiving the first user input selecting the permanent lock mode, present, on the remote computing device, a first authentication request;
in response to presenting the first authentication request, receive, from the remote computing device, a third user input including a first authentication token; and
activate the permanent lock mode only in response to receiving the first authentication token and when the first authentication token is valid.

### Claim 4 (depends on 3)

The system of claim 3, wherein receiving the first authentication token includes receiving a first authentication token selected from a group consisting of an alphanumeric password, a personal identification number, a biometric authentication, a Radio Frequency Identification (RFID) authentication, a Near Field Communication (NFC) authentication, and a security key insertion.

### Claim 5 (depends on 1)

The system of claim 1, wherein the electronic processor is further configured to:
in response to activating the permanent lock mode, disable at least one function selected from a group consisting of a unit toggle function, a unit lock function, and a unit view function.

### Claim 6 (depends on 1)

The system of claim 1, wherein the electronic processor is further configured to:
in response to activating the permanent lock mode, display, in the menu system, a locked indication for menu items corresponding to at least one function selected from a group consisting of a unit toggle function, a unit lock function, and a unit view function.

### Claim 7

A non-transitory computer-readable medium including instructions executable by an electronic processor to perform a set of functions, the set of functions comprising:
receiving, via a human machine interface for a medical scale, a first user input selecting a permanent lock mode;
in response to receiving the first user input, presenting a measurement unit selection prompt;
receiving a second user input selecting a measurement unit;
in response to receiving the second user input, activating, with an electronic processor, the permanent lock mode based on the selected measurement unit by setting a value in a memory of the medical scale;
detecting a reset dongle attached to an input/output interface; and
in response to detecting the reset dongle, deactivating the permanent lock mode by erasing the value without altering scale calibration data stored in the memory.

### Claim 8 (depends on 7)

The non-transitory computer-readable medium of claim 7, the set of instructions further comprising:
in response to receiving the second user input, presenting, a confirmation prompt;
receiving, via the human machine interface, a third user input; and
when the third user input confirms the selection of the permanent lock mode, activating the permanent lock mode based on the selected measurement unit.

### Claim 9 (depends on 7)

The non-transitory computer-readable medium of claim 7, the set of instructions further comprising:
in response to receiving the first user input selecting the permanent lock mode, presenting, via the human machine interface, a first authentication request;
in response to presenting the first authentication request, receiving, via the human machine interface, a third user input including a first authentication token; and
activating the permanent lock mode only in response to receiving the first authentication token and when the first authentication token is valid.

### Claim 10 (depends on 9)

The non-transitory computer-readable medium of claim 9, wherein receiving the first authentication token includes receiving a first authentication token selected from a group consisting of an alphanumeric password, a personal identification number, a biometric authentication, an RFID authentication, an NFC authentication, and a security key insertion.

### Claim 11 (depends on 7)

The non-transitory computer-readable medium of claim 7, the set of instructions further comprising:
in response to activating the permanent lock mode, disabling at least one function selected from a group consisting of a unit toggle function, a unit lock function, and a unit view function.

### Claim 12 (depends on 7)

The non-transitory computer-readable medium of claim 7, the set of instructions further comprising:
generating, on the human machine interface, a graphical user interface including a menu system; and
receiving the first user input by receiving the user input via the menu system.

### Claim 13 (depends on 12)

The non-transitory computer-readable medium of claim 12, the set of instructions further comprising:
in response to activating the permanent lock mode, displaying, in the menu system, a locked indication for menu items corresponding to at least one function selected from a group consisting of a unit toggle function, a unit lock function, and a unit view function.
