DESCRIPTION

According to an aspect of the invention, a straw for testing and preventing consumption of an unsafe beverage is provided. The straw may provide non-intrusive detection of drugs or other harmful substances in a beverage and may prevent a user from consuming the beverage if the beverage is deemed unsafe. The detection may be non- intrusive to avoid aggressive behavior from people in the vicinity of the user who may be suspicious or offended by the use of the straw. For example, the straw may have the shape and appearance of a common drinking straw to not draw attention to the use of the straw for drug detection purposes. The straw may couple to another device, such as a smartphone, for issuing automated and hidden alerts to the user, and in some instances, to a law enforcement organization. The straw may provide early detection of spiked beverages by scanning the beverage as soon as the straw contacts the beverage.

FIG. 1 is a perspective view of a straw for testing and preventing consumption of an unsafe beverage, according to examples of the present disclosure. Straw 100 may have a similar form factor as a common drinking straw. In some examples, straw 100 may include elbow 102 such that straw 100 may bend at elbow 102. In other examples, straw 100 may be curved into a shape. In some examples, straw 100 may be embedded in a beverage container. Straw 100 may include radio frequency (RF) interface 105, lightemitting diode (LED) 110, security circuit 115, control circuit 120, battery 125, one or more connection pads 130, liquid level sensor 135, one or more electrochemical sensors 140, and electrovalves 150a and 150b.

In some examples, the components of straw 100 may be divided between upper portion 160 and lower portion 165. Upper portion 160 of straw 100 maybe reusable while lower portion 165 of straw 100 may be a one-time use, disposable component. In some examples, lower portion 165 of straw 100 may be reusable after cleaning the components contained therein, such as electrochemical sensors 140.

RF interface 105 may establish a connection with near-by external devices (not expressly shown in FIG. 1), such as a smartphone or wearable device, to transmit information to the device. The information transmitted to the device may include audio recordings, images, video recordings, testing results, or any combination thereof. RF interface 105 may communicate with the device using any suitable RF protocol, such as Bluetooth, near field communication (NFC), MiWi, Wi-Fi, Z-Wave, or Zigbee. LED 110 may be used to provide notifications to a user of straw 100. For example, LED 110 may illuminate if the beverage into which straw 100 in placed is deemed unsafe. In some examples, straw 100 may omit LED 110 to allow the user of straw 100 to test a beverage more discretely.

Security circuit 115 may be used for proof of authenticity. For example, security circuit 115 may verify the compatibility of electrochemical sensors 140 with other components of straw 100. Additionally, or alternatively, security circuit 115 may be used to encrypt communications sent to an external device via RF interface 105. In some examples, lower portion 165 of straw 100 may include a security circuit (not expressly shown) to authenticate lower portion 165 of straw 100 when it is coupled to the upper portion of straw 100.

Control circuit 120 may be used to control the function of the components of straw 100. Control circuit 120 may be a central processing unit (CPU), a general purpose processor, a specific purpose processor, a microcontroller, a programmable logic controller (PLC), a digital signal processor (DSP), an application specific integrated circuit (ASIC), a field-programmable gate array (FPGA) or other programmable logic device, discrete gate or transistor logic, discrete hardware components, other programmable device, or any combination thereof designed to perform the functions disclosed herein. In some examples, straw 100 may include a real-time clock/calendar (RTCC) (not expressly shown). The RTCC may maintain accurate time, even when straw 100 is powered off. The RTCC may be used to time stamp events, such as the testing of the beverage or opening or closing of electrovalves 150.

Battery 125 may provide power to the components of straw 100. Battery 125 may be charged using one or more connection pads 130. In some examples, connection pads 130 may be electromagnetic to allow battery 125 to be charged using inductive charging. Connection pads 130 may be placed between upper portion 160 of straw 100 and lower portion 165 of straw 100. When upper portion 160 and lower portion 165 of straw 100 are uncoupled, connection pads 130 may be visible such that connection pads 130 may be coupled to a battery charging cable.

Connection pads 130 may be dual voltage and may also be used to establish a communication between the components on upper portion 160 of straw 100 (e.g., containing RF interface 105, LED 110, security circuit 115, control circuit 120, and batery 125) and the components on lower portion 165 of straw 100 (e.g., containing liquid level sensor 135, one or more electrochemical sensors 140, and electro valves 150a and 150b). Connection pads 130 may also be used to provide power to the components of lower portion 165.

Liquid level sensor 135 may detect the level of beverage in lower portion 165. When the amount of beverage in lower portion 165 is a sufficient amount available for testing, liquid level sensor 135 may send a signal to control circuit 120 indicating that sufficient beverage is present. In response to the signal, control circuit 120 may close electrovalve 150a to stop the flow of the beverage through straw 100.

Electrochemical sensors 140 may be used to test the beverage for one or more substances such as drugs or other harmful substances. Straw 100 may include one or more electrochemical sensors 140. A given electrochemical sensor 140 may test for the presence of a given drug or harmful substance or a given electrochemical sensor 140 may test for the presence of a variety of drugs or harmful substances. For example, straw 100 may include electrochemical sensor 140a for testing for drug A, electrochemical sensor 140b for testing for drug B, and electrochemical sensor 140c for testing for drug B. As another example, straw 100 may include one electrochemical sensor 140 that tests for drug A, drug B, and drug C. In some examples, electrochemical sensor 140 may include an isolation channel to isolate the portion of the beverage tested. An isolation channel may be used in circumstances where electrochemical sensor 140 may influence the beverage during testing.

Electro valves 150a and 150b selectively allow and disallow the beverage to flow through straw 100. For example, after straw 100 is placed in a beverage, electrovalves 150a and 150b may be opened to allow the beverage to flow through straw 100 until the beverage reaches liquid level sensor 135. When the beverage reaches liquid level sensor 135, liquid level sensor 135 may send a signal to control circuit 120 and control circuit 120 may close electrovalve 150a or 150b to prevent the beverage from flowing further upward and being consumed by the user. After the beverage has been tested, if the beverage is deemed safe for consumption, control circuit 120 may open electrovalve 150a or 150b to allow the beverage to flow through straw 100 to the user. If the beverage is deemed unsafe, electrovalve 150a or 150b may remain closed. Additionally, control circuit 120 may close the other electro valve 150a or 150b to trap the liquid sample in lower portion 165 of straw 100 to preserve the sample for additional testing at a later time or as evidence to provide to a law enforcement organization.

In some examples, straw 100 may additionally include one or more cameras or microphones (not expressly shown) to record the surrounding environment. The camera, microphone, or any combination thereof may be activated by control circuit 120 after the beverage is deemed unsafe. For example, control circuit 120 may activate a camera to record video of the surrounding environment to capture an image of a person suspected of placing the drug or harmful substance in the beverage.

In some examples, straw 100 may additionally include an accelerometer (not expressly shown) to detect movement, rotation, or any combination thereof. Straw 100 may further include an activation circuit (not expressly shown) to allow a user to manually open electro valve 150a, electro valve 150b, or any combination thereof. In some examples, a user may activate electrovalve 150a, electrovalve 150b, or any combination thereof using an application on the user’s device (e.g., a smartphone or wearable device).

If electrochemical sensors 140 test the beverage and determine the beverage is unsafe, control circuit 120 may communicate the test results to an external device, such as the user’s smartphone or wearable device, via RF interface 105. An application executing on the external device may provide a discrete notification to the user that the beverage is unsafe (e.g., a notification on the smartphone or wearable device). Additionally, or alternatively, the application may alert a law enforcement organization. The application may communicate with the law enforcement organization via an authenticated and encrypted communication channel. The application may provide the law enforcement organization information on the circumstances of the detection of an unsafe drink, such as an identification of the user, the user’s geolocation, an identification of the substances detected during testing, voice recordings, images, video recordings, or any combination thereof. In some examples, the application may alert other individuals designated by the user, such as a family member or friend of the user.

FIG. 2 is a block diagram of a system for testing and preventing consumption of an unsafe beverage, according to examples of the present disclosure. System 200 may include straw 202 and user device 280. Straw 202 may be similar to straw 100 shown in FIG. 1. Straw 202 may include RF interface 205, control circuit 220, connection pads 230a and 230b, liquid level sensor 235, electrochemical sensor 240, electrovalves 250a and 250b, and electrical contact 270. The components of straw 202 may be divided between reusable portion 260 and disposable portion 265. In some examples, disposable portion 265 may be reusable after cleaning the components contained therein, such as electrochemical sensor 240.

RF interface 205 may establish a connection with user device 280, to transmit information to user device 280. The information transmitted to the device may include audio recordings, images, video recordings, testing results, or any combination thereof. RF interface 205 may be similar to RF interface 105 shown in FIG. 1.

Control circuit 220 may be used to control the function of the components of straw 202. Control circuit 220 may be similar to control circuit 120 shown in FIG. 1.

Connection pads 230a and 230b may facilitate communication between reusable portion 260 and disposable portion 265 and provide power to the components of disposable portion 265. Connection pads 230a and 230b may be similar to connection pads 130 shown in FIG. 1. Connection pad 230a may be placed on reusable portion 260 and connection pad 230b may be placed on disposable portion 265.

Liquid level sensor 235 may be similar to liquid level sensor 135 shown in FIG. 1 and may detect the level of beverage in disposable portion 265. When the amount of beverage in disposable portion 265 is sufficient for testing, liquid level sensor 235 may send a signal to control circuit 220 via connection pads 230a and 230b indicating that sufficient beverage is present. In response to the signal, control circuit 220 may close upper electrovalve 250a or lower electrovalve 250b to stop the flow of the beverage through straw 202.

Electrochemical sensor 240 may be used to test the beverage for one or more substances such as drugs or other harmful substances. Electrochemical sensor 240 may be similar to electrochemical sensor 140 shown in FIG. 1.

Electro valves 250a and 250b selectively allow and disallow the beverage to flow through straw 202. For example, after straw 202 is placed in a beverage, electrovalves 250a and 250b may be opened to allow the beverage to flow through straw 202 until the beverage reaches liquid level sensor 235. When the beverage reaches liquid level sensor 235, liquid level sensor 235 may send a signal to control circuit 220 and control circuit 220 may close upper electrovalve 250a or lower electrovalve 250b to prevent the beverage from flowing further upward and being consumed by the user. After the beverage has been tested, if the beverage is deemed safe for consumption, control circuit 220 may open upper electrovalve 250a or lower electrovalve 250b to allow the beverage to flow through straw 202 to the user. If the beverage is deemed unsafe, upper electrovalve 250a or lower electrovalve 250b may remain closed and control circuit 220 may close the other of upper electro valve 250a or lower electro valve 250b to trap the liquid sample in disposable portion 265 of straw 202 to preserve the sample. Electrovalves 250a and 250b may be similar to electrovalves 150a and 150b, shown in FIG. 1.

Electrical contact 270 may be an activation circuit to allow a user to manually open upper electro valve 250a, lower electrovalve 250b, or any combination thereof. Electrical contact 270 may be a button, switch, or any other suitable mechanism used to send a signal to control circuit 220 to cause control circuit 220 to open upper electrovalve 250a, lower electrovalve 250b, or both, and allow the beverage to flow through straw 202.

If electrochemical sensors 240 test the beverage and determine the beverage is unsafe, control circuit 220 may communicate the test results to user device 280. User device 280 may be any suitable electronic device, such as a smartphone or wearable device. An application executing on user device 280 may provide a discrete notification to the user that the beverage is unsafe (e.g., a notification on user device 280). Additionally, or alternatively, the application may alert a law enforcement organization. The application may communicate with the law enforcement organization via an authenticated and encrypted communication channel. The application may provide the law enforcement organization information on the circumstances of the detection of an unsafe drink, such as an identification of the user, the user’s geolocation, an identification of the substances detected during testing, voice recordings, images, video recordings, or any combination thereof. In some examples, the application may alert other individuals designated by the user, such as a family member or friend of the user.
